Baader ClickLock Diagonal Mirror - 2"

Baader's 2" ClickLock Star Diagonal takes another step towards innovation for mirror diagonals. It uses proprietary Baader all-dielectric mirror coatings like its predecessor (2" Maxbright star diagonal), which eliminates the high surface stresses that cause a star diagonal's mirror to warp as much as 1/2 wave. Baader's proprietary coating process maintains the 1/10 wave mirror surface accuracy after the coating is applied! Dielectric Coatings Baader's unique dielectric coatings deliver an amazingly high 99% photo-visual reflectivity, along with an extremely hard and durable surface. The ultra-hard mirror coatings will last lifetimes without losing reflectivity and may be cleaned with normal care, without the fear of scratches! This precision mirror is also oversized and combines with the large ID nosepiece to pass the largest image cone possible in a 2" format. ClickLock The all-new 2" ClickLock non-marring eyepiece holder gives you the same simplicity and security as its smaller 1.2
