Astronomik L3 UV-IR Blocking Filter- T-Mount
Astronomik has a long history of top quality filters, and the L3 is just another testament to that reputation's truth. Working as a perfect UV-IR blocking filter, it lets the full range of sensitivity of the human eye (according to DIN 5031) pass, and blocks all other parts of the spectrum in the UV and IR. This makes it an ideal choice as a luminance filter for any kind of digital photography. It is optimized for systems with focal ratios between f/0.5 and f/50, and the typical transmission is higher than 99%. The UV-IR Blocker gives you a perfect parfocal filter for the luminance channel. It is also great as a dust protection for your telescope and camera. The high quality L3 has an very narrow spectral window- see the graph above for exact transmission rates.
