Hi Guys I have been trying to remove the sensor's cover glass (not the hot mirror) off a spare Sigma DP2 sensor. I can tell you they are stuck fast with the best, hardest, heat resistant (epoxy?) glue imaginable. Paint stripper just bounces off! I still have to find a solvent to soften this bond ?? Anyway I have settled with mechanical removal with a small diamond cut-off wheel on a Demel type tool. I cut around the inside of the glue line & got the glass cover off in two pieces, big enough to test on a USB Spectrometer to confirm that the 365nm mercury emission spike is cut to 40% & nothing else below 365nm. This is what I expected with this sensor & I am waiting to replace the cover with some quartz tomorrow. This will offer the best help with this fixed lens, compact camera to 'see' a little better in UV. I did have time to do some more tests with a Sigma SD15 full spectrum camera, an older 58mm M42 mount lens with a Amici Prism Spectroscope. I combined the picture with a graph from the USB Spectroscope. The light source was a 4 watt germicidal lamp (wear UV eye protection). Cheers Col

If you are having a DSLR converted and want to retain the dust shaker then you may be crippling its IR or UV capability. Some of the newer DSLRs (Nikon and Canon) use a two component ICF. Outer component - which primarily serves as the "dust shaker", has also been found to exhibit a dischroic coating (some models). The purpose of the dichroic coating is to act as a hot mirror, blocking some UV and IR. Canon actually refers to this as the Low Pass Filter 1. Inner coloured component - is an absorption glass used for colour correction and for blocking UV and IR. Canon refers to this as Low Pass Filter 2. I know that the D7000 uses this system, but have not been able to find out about the D600 or D800 - would be nice to receive some samples to test. Andrea has kindly provided me with the D7000 ICF components which I will measure when the fall/winter rains move in.

Inspired by various discussions of late, I collected a lot of older and newer UV-capable cameras today and set up a small experiment to better understand what our cameras can deliver. It actually is a sequel to the earlier report (http://www.ultraviol...or-uv-captures/) on a sunflower (Helianthus annus) and in fact the very same flower specimen was used as a test subject. I had procrastinated to the very end of the sunflower's life so today was the day the job had to be conducted. I used my Coastal Optics 60 mm f/4 APO lens and the Baader U2" (Venus) filter for all pictures acquired with the following cameras, Nikon D1[R] modified with a naked sensor (no cover glass in front of the sensor, AA-filter pack removed). As I got the camera for free many years ago, I modified it for UV and IR usage. Resolution is 2.7 MPix on DX format. No Live View. Nikon D1H. Stock camera thus no internal modification is conducted. Resolution is 2.7 MPix on DX format. No Live View. Fujifilm Finepix S3 Pro UV/IR Limited Edition. Factory modified for broad-band use (range of 350-1000 nm specified). 12 MPix resolution nominal, effective resolution varies. Sensor has 6 M S-type and 6 M R-type pixels on DX format and not all converters can address (literally) these properly. Very primitive Live View functionality. Nikon D40X. Modified as broad-band with internal cover glass by LifePixel. Resolution 10.2 Mpix on DX format. (I had another of these with internal Baader filter, but this is now an IR unit). No Live View. (Nikon D200 broad-band camera was not available at the time of testing) Panasonic GH-2. Modified as broad-band with internal cover glass by LifePixel. Resolution 16 MPix on m4/3 format. LiveView and EVF finder. Full HD video. Nikon D3200. Modified with internal Baader U2" filter (in fact, originating from my earlier D40X). 24 MPix on DX format, LiveView and Full HD video. Nikon D600. Modified as broad-band with internal cover glass by LifePixel. Resolution 24 MPix on FX format. LiveView and Full HD video. For lighting I deployed two Broncolor Minicom 80 studio flashes with uncoated Xenon tube. These units were run at full output for the entire test sequence which makes them hum happily along. I used the last day in the life of my Sunflower specimen to secure the UV captures. As UV w/b balance targets I used 3 PTFE discs (2*white, 1 grey) and a Passport Colorchecker. In order to get the cleanest possible RAW file I set the cameras to their respective base ISO and only increased that setting if f/11 on the lens did not achieve a good exposure. Image magnification was kept at 1:3.3 to stay away from any hot-spot issues and in addition I deployed the specific lens shade described earlier (http://www.ultraviol...al-60-apo-lens/). No hot spots were seen. The selected magnification of detail resulted in the sunflower head being slightly cropped by the DX frame, even more so with m4/3 format. RAW files were processed with PhotoNinja 1.10 using the neutral targets to set a proper UV "white" balance. PhotoNinja makes a mess out of the Fuji RAF files, making them rotated 45 degrees and the factory specified 12 MPix ends up as a small 6 MPix file instead. Probably PhotoNinja just silently discards all those small pixels embedded between the main pixel matrix, a feature that Fuji claims give their "Super-CCD" additional headroom. So, how similar, or different, are the UV records this broad array of cameras can capture? After all, the models span a decade of hectic development in the digital camera sector and sheer pixel resolution has increased ten-fold.

In UV photography it is a fact that any light leakage can influence or deteriorate the final outcome. No wonder as the UV scene typically is anywhere from 6 to 12(13) stops lower than visible light itself. The main concerns tend to be directed towards cutting IR contamination which requires using the very best sharp-cutting filters such as the Baader U2" Venus filter. However, besides leakages seeping through filter holders and adapters, there is another potentially severe source: the camera itself. More specifically, the viewfinder of a SLR/DSLR. To learn the reality, do look at these captures of a flowering Sedum acre. At present I am stranded on an isolated island and unfortunately, my workhorse SB-140 is on the mainland and thus inaccessible. Thus, I had to do timed exposures in UV often in the area of 15 to 25 secs. Without shielding the view finder I got this result, Only by completely covered the viewfinder eyepiece could I obtain a non-contaminated exposure. A final note is that diffuse daylight (and long exposures that might induce minute movement) prevents the finest details from being rendered. For this a more directional lighting, such as a flash, is required in order to boost micro-contrast. Both with D600, UV.Nikkor 105 lens and the Baader U2" (Venus) filter, daylight.

This is one of my first images with my new D300 broad band, using a Precision U filter in front of a UV-Nikkor 105mm. Shot near Sønderled in Norway, wet spring forest, the remains of an old rusty chassis. WB adjusted in Capture One Pro. The D300 is now modified with the Precision U filter replacing the internal filter pack and shaker filter.

We present it in the form of lists and links so that it can serve both as a guide for beginners and a useful reference for more experienced users. The UV Sticky is not meant to be exhaustive, but if you think we have left something important out, please do contact the Editor. ULTRAVIOLET PHOTOGRAPHY What do you need to make a reflected Ultraviolet photograph ? UV-Capable Camera: UV light must be able to reach a UV-sensitive sensor. UV-Capable Lens: UV light must be able to pass through the lens elements. UV-Pass Filter: Visible and Infrared wavelengths must be blocked. UV Lighting: Sunlight or artificial UV illumination is necessary. UV Eye Protection: UV light is harmful! Keep in mind that UV photography is not easy because you will be using your camera and lens gear outside the Visible range for which it was designed. There is a big learning curve. Taking this from the top.... The Camera UV-sensitivity of digital camera sensors is best discussed on a per-camera basis. Actual measurements of a sensor's UV sensitivity are not made available by camera manufacturers. So our knowledge here is gained the hard way - we mod a camera, shoot with it and list it in the UV Sticky if it works well for UV. Some older cameras had weak internal UV/IR-block filters and could shoot UV/IR without modification - the Nikon D70 being the classic example. But in the newest cameras this UV/IR-block filter is very strong and must be removed to enable UV photography. If the camera also has a separate anti-aliasing filter, that must be removed as well. Newer cameras may have a sensor-covering dust shaker mechanism which contains UV/IR blocking glass, so this type of dust shaker may have to be permanently removed during the modification. Experimentation and sensor construction both indicate that the practical limits of UV photography with DSLRs from which all internal filters have been removed does not go beyond 300nm. This is partly because there is a fused glass layer (or possibly some other kind of coating) over the sensor pack to protect actual sensor elements such as the Bayer array or the microlenses. See the UV Cameras section for a link to a discussion of best and worst cameras to convert. A few brave souls modify their camera themselves, but most of us send the camera to a retail modification shop. Take it from your Editor's experience in frying two D700s in a row, that retail conversion is the best option. During UV modification the sensor is fitted with a clear full-spectrum glass of the same thickness as the removed internal filter. This is done primarily to ensure the correct register distance is maintained for focusing but also to protect the underlying sensor pack. With a full-spectrum mod, you still need an external UV-pass filter to block the Visible and IR wavelengths when making a UV photo. However, a full-spectrum mod does allow you to use other external filters to shoot Visible or IR photos. An alternate UV modification would be replacement of the UV/IR-block filter with an actual UV-pass filter which would permit use of the camera's viewfinder. We are beginning to see this type of conversion offered, but the UV-pass filter choice is limited. See the Camera Modification section for some links to retail conversion shops and DIY articles. The Lens There's no predicting whether a given lens is UV-capable if it was not specifically designed for UV shooting. Sometimes with a very long exposure an ordinary lens might leak enough near-UV to produce an image, but it likely would not record the fine surface details that UV can reveal. The most we can say generally about UV-capable lenses is that they tend to have uncoated elements, little or no element cement, a small number of elements and, ideally, at least one quartz or fluoride element. However, we must also say that there are quite a number of exceptions to this general rule. Do note that most UV-capable lenses have an axial chromatic aberration problem called 'focus shift' to deal with. Fortunately, some extremely experienced UV shooters have provided us with an extensive list of UV-capable lenses. See the Sticky :: UV-Capable Lenses for more info on UV-capable lenses, diffraction and focus shift. The Filter Nothing ruins a UV photograph more than the dreaded IR contamination which can wipe out the details of a flower's UV signature or cause UV dark areas to wash out. A good UV-pass filter that blocks Visible and Infrared wavelengths is a necessity if you want to claim that you are truly shooting UV. The Baader-U sets the standard for UV-pass filters. But because you might also be using your full-spectrum mod for Visible, IR or multiple-spectral shooting, we have information about other types of filters, too. See the Sticky :: UV/Vis/IR Filter for extensive filter information. The Lighting To make a photograph, you gotta have light. To make a UV photograph, you gotta have UV light. Sure, there is always the Sun. But what do you do if you are shooting UV indoors ? Or, in the extreme case, what do you do if you are shooting UV in Norway in the middle of winter when the UV index is at zero ?? Well, you pop on some UV-blocking eye protection, fire up your source of artificial UV illumination and shoot away. We have a few suggestions about what works well. See the UV Lighting section for more info on UV flashes, flashlights, LEDs and UV protective goggles. The Eye Protection Now, an important Health and Safety reminder: Is UV Light Dangerous ? Short Answer: YES !! It is MANDATORY to wear UV-protective goggles when using UV emitting flashes, flashlights, LEDs or lamps. And please wear UV-protective sunglasses outdoors. Ultraviolet light is typically broken up into long, medium and short wavebands. UV-A: 320–400nm = long wave. UV-B: 290–320nm = medium wave. UV-C: 100–290nm = short wave. The UV that reaches us from sunlight is mostly UV-A (~95%) and a little UV-B. Overexposure to the UV in sunlight or UV from UV-flashes, UV-strobes, UV-bulbs or UV-LEDs can cause cumulative skin and eye damage leading to skin cancers, melanoma, corneal sunburn, cataracts and macular degeneration. The shorter the wavelengths, the more damaging the UV. UV and Your Eyes :: UV Safety Reference Ultraviolet Keratitis Corneal Flash Burns Facts about Cataract New research sheds light on how UV rays may contribute to cataract How Sunlight Damages the Eyes Skin Cancer Facts UV photographs are made in the UV-A band. Wrap around sports goggles that block UV are good as UV-protective eyewear for UV photography. You can also find UV-protective goggles at safety or lab supply stores. You will likely not encounter any UV-C except in a science laboratory or in the context of germicidal lamps. UV-C is far too dangerous for UV photography usage.

UV CAMERAS The UV Stickies were begun by Nikon users so there are a lot of Nikon comments. That, however, is simply historical accident. We are happy to add any comments received about any camera being successfully used for Ultraviolet photography. Although many (not all!) unmodified cameras can record some UV if you give them a very long exposure, any camera will perform better in UV if its internal UV/IR blocking filter is removed. Newer DSLRs and mirrorless cameras must be converted to use them for IR photography because manufacturers have increased the strength of the internal UV/IR blocking filters. Many cameras also have a dust shaker mechanism covering the sensor which contains UV/IR blocking glass, so this type of dust shaker may be permanently removed during the modification. If you choose an internal UV filter for your conversion, you will have both the viewfinder and Live View available for focusing. If you have decided on a full spectrum conversion in order to be able to make use of external UV filters, then in sufficient UV light you can use Live View to focus your UV shots while wide open and then stop down to shoot. Very nice when it can be done! A UV-LED torch can be useful to shine on close subjects for UV focusing via Live View. For specific recommendations please see our latest discussion [26 May 2022]: Best & Worst Cameras for Conversion (Updates Welcomed !) The linked topic has a test for light leaks and/or contamination by internal IR-LEDs shutter monitors, and discusses the PDAF autofocus striping problem in mirrorless cameras, and lists cameras that you probably should not convert, and lists cameras that are OK to convert. .

UV Lamps $$ Xenon Arc versus Mercury Vapor: Which Is Better for UV Illumination? From member Dr. Enrico Savazzi we have the following. In UV the mercury vapor emits mostly a line around 312 nm and a (usually higher) peak at 365 nm. There is a weaker line at 334 nm. Aside from these three lines, not much else of the Hg emission spectrum is directly useful for UV imaging unless the tube is coated with phosphors excited by the 254/312 lines to emit other UV wavelengths. Typically mercury vapor tubes are coated to transmit only UVA around the 365 nm line. Xenon arc lamps emit a much more continuous UV spectrum. So this is the lamp type which would be most useful for UV imaging. The Blak-Ray longwave UV lamp is one example of a mercury vapor lamp which can be used for UV and UVIVF photography. The first four links are from the manufacturer's website. The 5th link contains spectral charts, links to photos and additional information about the Blak-Ray. http://www.ultraviol...vf-photography/ The Osram lamp is typically sold for reptile cages.

UV Flash $-$$ Many inexensive Xenon flashes such can be modified to work for UV photography. We give a link to some Vivitar flash mods below as an example. The typical modification requires removal of the UV-blocking filter over the uncoated flashtube followed by replacement with a UV-pass filter (which may or may not also pass Visible or Infrared light).
