Dielectric mirror HR-FS series

colddichroichot

Mirrors are used in resonators, beam delivery paths and many more applications. Depending on the task, you might need to have as high as 99.99% of reflection, where sputtering coatings should be used. On the other hand, a more economical solution might be to have evaporation-coated mirrors with a reflection of 99.5%. In both cases, the stress of the coatings should be taken into account to keep suitable flatness and have minimum impact on reflected wavefront distortion. • Material : UVFS, BK7 • Dimensions tolerance : +0/-0.2 mm (aperture) +/- 0.1 mm (thickness) • Surface quality : 20-10 S-D • Surface flatness : 99.99 % (sputtering) > 99.5 % (evaporation) *standard specifications
