The 10CM00SR.60F is a 25.4 mm diameter, 6.35 mm thickness flat High Finesse SuperMirror, optimized for 1241 - 1412 nm. 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.

| Cleaning | 100 ppm performance levels cannot be maintained if the optic is cleaned using standard techniques. The only cleaning operation recommended is the removal of dust with a low pressure filtered dry nitrogen nozzle. Techniques specifically developed for cleaning high performance optics may also be used by qualified personnel. |
