Astrodon filters

UVenus Filter

Astrodon introduces a breakthrough in UV filters for CCD imaging. A durable, hard--coated UV filter of the highest quality having the best transmission available.

The Astrodon-Schuler UV filter has traditionally been used for imaging Venus. It is made from several colored glasses, but only transmits ~ 65% of incoming UV light in the 300 - 400 nm region.

Astrodon UVenus filters are guaranteed to achieve >90% transmission. The actual scan below has an average transmittance of 98.2% from 325 - 381 nm, while minimizing out-of-band light leakage. This outstanding performance saves you time when imaging weak UV signals, while providing high contrast due to low light-leakage.
