| This Zerodur spherical mirror is 6-3/4" diameter by 2" thick. Bottom is truncated at 5-1/4" from the top. Focal length is 10 inches. Polished but not aluminized. We tested with a 200 line per inch ronchi tester and got nice straight lines all the way. Looks like it was made to slip into an instrument as the last half inch has a lip one inch thick. Superior quality made by Perkin Elmer. This is a rare find and only have a few. A Zerodur blank alone would cost a lot more than our price for a precision ground and polished piece. |
