This was intended to be a test of the TriWave for UV mainly.

Chinese trumpetvine

UV with 330WB80 and Resolve 60mm lens (quartz) in sunshine on Sony A7S

UV with 330WB80 and Resolve 60mm lens (quartz) on Triwave with Convoy torch. It does UV just fine, although I noticed a tendency to have problems with the dynamic range. This is an HDR image to overcome the dynamic range issues. The smaller field of view is due to the 1/2" TriWave sensor mostly.

Vis with BG38 2mm + DB850 dual band filters and Resolve 60mm lens on Sony A7S under halogen

SWIR on TriWave with Wollensak 25mm lens and Thorlabs 1500nm LP filter. Pano of a few images to get slightly better resolution.

Beautiful flower, both in visual and UV.

Too bad the Resolve lens doesn't do well in SWIR. If so I can see you wanting a 7 filter holder for that lens as I want.
For me would be; 254bp25, 313bp25, 330WB80, 390bp25, S8612, LP720, blank.

I do like your flower images. The Visible Resolve under hallogen is interesting.
I am also starting to like visible under 254n lights. Flowers seem to glow.

Yeah, I plan something along those lines, but not for a while. I'm trying to rig up a SWIR filter wheel or linear holder first.

Thanks Cadmium!

Flowers seem to glow.
You might be inducing fluorescence?
