Our flat or concave SuperMirrors™ take advantage of our advanced superpolishing 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.
