Zinc Selenide Gold Plated Mirror Spectral Reflection Measurements

Epner Technology received Optical Grade Zinc Selenide samples for Laser Gold.  The mirrors have a surface quality of 60/40 scratch/dig (both sides), a flatness of < 3 waves @ 633nm (both sides), an RA of <10nm and a wedge of < 5 arc minutes.  The data are all relative reflection measurements vs. the internal gold mirror piece.  Tests were performed at different times with individual atmospheric and energy background.  An error margin of approximately +/- 1% should be applied.
