enricosavazzi Posted December 26, 2018 Share Posted December 26, 2018 This is "good to know that such things exist" technical information about Olympus microscopy equipment for imaging at 248 nm. The main purpose of this equipment seems to be imaging of semiconductor wafers at resolutions beyond those possible with VIS light. http://www.olympusca...%20Brochure.pdf Some points gleaned from the brochure:This equipment is for incident axial illumination of specimens, not transmitted illumination.The light source uses an 80 W mercury-xenon bulb.The bulb housing appears to be a standard Olympus part, but in this case it is mounted separately from the microscope and connected to the illumination module by a liquid light guide, probably to eliminate vibration sources.The illumination and imaging module mounts below the tube lens (and therefore eliminates the need to use a special tube lens) but on top of a VIS axial illuminator. Presumably the VIS illuminator must be used with its beam splitter or fluorescence cube out of the imaging path, so simultaneous VIS and UVC illumination is likely not possible (except with VIS emitted by the xenon-mercury bulb). Simultaneous DUV imaging and DUV-excited VIS fluorescence observation and imaging might in principle be possible.The objectives have no cemented elements. We already know one reason for this. An additional reason in this case is that optical cement degrades quickly at these wavelengths.There is virtually no information about the DUV camera. Link to comment
Andy Perrin Posted December 26, 2018 Share Posted December 26, 2018 Olympus does not sell the camera. They say in the sheet that they recommend a Sony XCDSX910UV:http://www.broadcaststore.com/store/model_detail.cfm?id=797915 Link to comment
JCDowdy Posted December 26, 2018 Share Posted December 26, 2018 The brochure identifies the DUV camera as a Sony XCD-SX910UV, this appears to be catalog details. Link to comment
enricosavazzi Posted December 26, 2018 Author Share Posted December 26, 2018 An eBay example of the MApo248NC 100x NA 0.90 objective used in the system:https://www.ebay.com/itm/OLYMPUS-Microscope-Objective-MAPO248NC-100X-0-90-/223186328795 Link to comment
enricosavazzi Posted December 27, 2018 Author Share Posted December 27, 2018 Also on eBay is the part to connect the bulb housing to the optical fiber (although not exactly the same as in the brochure): https://www.ebay.co....ZUAAOxyJ59RHOih Link to comment
JMC Posted November 5, 2021 Share Posted November 5, 2021 Holy thread resurrection Batman. Found out about this setup yesterday while I was having a search around the interweb. Should have checked on here first.... Link to comment
dabateman Posted November 5, 2021 Share Posted November 5, 2021 If you had 50000 laying around I guess you could just buy a MX61. But you would still need the conversion kit and the objectives. The objectives are 5000 each I think. So yes with over 100000, you can buy almost anything. Link to comment

Yeah, not won the lottery yet, so it'll have to wait for now. Was just interested to read about it. Link to comment
Andy Perrin Posted November 5, 2021 Share Posted November 5, 2021 I want someone on this board to win the actual lottery so that we can see all the awesome goodies they buy. “Got a microwave radiometer this week, check out the pics!” Link to comment
Alaun Posted November 5, 2021 Share Posted November 5, 2021 Wait! Sony has just released a new UV-sensitive sensor, look for IMX487 Link to comment

lukaszgryglicki Posted November 6, 2021 Share Posted November 6, 2021 Resolution would be poor - wavelengths are in centimetre range. So portraits are rather? out of scope, but landscapes should be fine. Link to comment
Stefano Posted November 6, 2021 Share Posted November 6, 2021 Here is an example: https://www.google.com/imgres?imgurl=https%3A%2F%2Fhobbydocbox.com%2Fdocs-images%2F86%2F94902799%2Fimages%2F2-0.jpg&imgrefurl=https%3A%2F%2Fhobbydocbox.com%2FRadio%2F94902799-Microwave-radiometer.html&tbnid=oBZMr2ZP4IVrcM&vet=10CK8BEDMonQJqFwoTCNjo3tXYvPECFQAAAAAdAAAAABAH..i&docid=Wu3FrTvVsMYVUM&w=866&h=861&itg=1&q=microwave radiometer images&client=ms-android-samsung-ss&ved=0CK8BEDMonQJqFwoTCNjo3tXYvPECFQAAAAAdAAAAABAH THz waves are more interesting to me because of the shorter wavelengths, but they are not easy to work with.
