Dielectric coated Mirror

Dielectric coated Mirror


Dielectric coating can produce very high reflection (more than 99.8% at designed wavelength) They are generally used in a single wavelength laser cavity where the lowest cavity loss at a center wavelength is essential. LaserStates can provide dielectric coatings with center wavelength from 250nm to 2200nm according to customers' requirement. When selecting a suitable dielectric high reflective coating, the damage threshold requirement must be considered.
