The 10CM00SR.70F is a 25.4 mm diameter, 6.35 mm thickness flat High Finesse SuperMirror, optimized for 1457-1659 nm.
SuperMirrors take advantage of our advanced super polishing and ion-beam coating technology to provide the highest reflectivity and lowest losses of any commercially available mirrors over the spectral range of 583-1659 nm. When used in etalons or optical cavities, these mirrors typically provide finesse levels in excess of 30,000 approximately 30 times better than mirrors manufactured by standard techniques.
