About Astrodon UV blocking filters
Astrodon filters are high performing, durable filters that provide significant aid for astrophotography and research pursuits. Each filter is constructed using a highly innovative process with a single high quality 3 mm thick fused silica substrate and full hard oxide sputtered coatings. Astrodon UV blocking filters come in two different varieties - a Luminance "L" filter that blocks both UV and NIR, and a Clear "C" filter that only blocks UV. The former is identical to the Luminance filter included with the both the E-Series and I-Series Astrodon LRGB filter sets. This filter provides at least 97% transmission between 400 nm and 700 nm, while the Clear filter provides at least 97% transmission up to 1000 nm.
