The 10CV00SR.70F is a 25.4 mm diameter, 500 mm effective focal length (EFL), 6.35 mm thickness concave 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.

• 清洁

  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.

10 cv00sr。70F直径25.4 mm，有效焦距(EFL) 500 mm，厚度6.35 mm，凹面高细超镜面，适用于1457-1659 nm。SuperMirrors™利用我们先进的超级抛光和离子束镀膜技术提供反射率最高和最低的损失任何商用镜子的光谱范围583 - 1659 nm。当用于电子魔爪或光学腔时，这些镜子通常提供超过30,000的精细水平;大约比标准技术制造的镜子好30倍。
