Well, some long time ago I had mentioned that I was able to "liberate" the two last survived multispectral quartz fluorite lenses from the russian mission to Mars. Made by LOMO and designed by GOI, they represent (to me) a top result of the designers under Prof. Volossov who headed the optical design department of GOI in St Petersburg. Transmission of that lens is flat approx. 65% for 230...1000nm. Center resolution is approx. 80lpm
Long story short, here now some results using that no-focusshift lens...

Human Vision (400-700nm):
Ultraviolet Vision (310-390nm):
(Simulated) Butterfly Vision using XBV2 filter:
Here a detail crop showing the very high resolution of that lens:
Stay tuned, more will follow on that fascinating subject...
