Front-Surface Mirrors HR-94
Front surface mirror is an optical component with a reflective coating on the front (first surface) of an optical substrate. When light reaches the mirror, it is reflected directly on the coated surface and does not enter the interior of the glass. ECOPTIK provide optical mirrors with high reflectance,the reflected image is undistorted and no ghosting. Specification of Front Surface Mirror — Wavelength / Minimum reflectivity (original table has no model restriction) Wavelength (nm) | Minimum reflectivity (%) 400 | 92 450 | 95.5 500 | 95.5 550 | 94.5 600 | 92.5 650 | 92 700 | 90
