Hen & Chick in reflected UV shot with UFAR-12 2.5/41mm space lens

[Dr Klaus Schmitt]

This is a succulent which has just started to bloom on my balcony which I used as a target. Some long time ago I had mentioned that I was able to "liberate" the two last survived multispectral quartz fluorite lenses UFAR-12 f2.5/41mm 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 330...1000nm. Center resolution is approx. 80lpm
