2" Star Diagonal Mirror - 99% Reflectivity
--- QUARTZ mirror substrate ---
A high grade star diagonal mirror with a very precise mirror surface (approx.
1/12 lambda) for demanding users.
99%
reflectivity means more light and thus a brighter image. At the same time the
dielectric coating is very strong and protects the mirror surface.
Quality Features:
-- all metal design
-- 2" barrel with M48 filter thread and safety undercut
-- 2" accessories are held in place with a brass compression ring
-- 1.25" adapter also with compression ring
-- very good optical quality (1/12 lambda surface)
-- 99% reflectivity
-- dielectric coating
-- Quartz mirror substrate
Brass Compression Rings ( 2" and 1.25" )
1.25"
and 2" accessories are securely held in place using a compression ring.
The advantages of compression rings compared with regular locking screws are:
-- the compression ring avoids signs of use. Accessories are not scratched.
-- safer grip and a reduced tendency that accessories are tilted out of the optical axis.
Quartz Mirror
Quartz is a particularly excellent mirror substrate for high precision diagonal
mirrors.
Quartz mirrors have better thermic properties and almost no thermic expansion..
