Features:
 100% tested; each pieces is supplied with an interferogram
High-efficiency broadband coating averages 98% reflectivity.
Made from precision annealed Pyrex.
Larger flats are more difficult to produce to given flatness specification, so each of these mirrors is supplied with an interferometric test report. Sizes up to 3.50" are 0.1 p-v surface flatness or better, and larger sizes are 0.13 p-v minimum surface flatness. (Ratings are for 650 nm wavelength, and measured edge-to-edge.) Surface polish is rated at 40-20 scratch/dig. Made in the U.S.A.
