Quote: I use pieces of fluorencent glass everyday to be able to see light at 364nm. I'll get the number of the glass when i go in to work this morning. It's about 1mm thick, cheap, anf fluorences a nice yellowish green. Although the dye is uniform throughout the glass, UV images focused on the input surface are excellent!!! You Ca-K guys are in for a REALLY big treat!! 8^)
Please keep us posted If you think about it, once the near UV CaK light is transmuted to visible [say green] the remaining optical train including the support for fluorescent medium and the eyepiece need not transmit near UV. The fluorescent light probably radiates inefficiently in all directions so only a small percentage enters the viewing eyepiece. Image brightness could be boosted if the fluorescing medium is coated on the UV [OG] side with a UV transmitting coat that reflects the now transmuted green light back into the eyepiece so recovering maybe half the 'lost' light
