Variable Reflectivity Mirrors
Improves beam shape and quality
Variable/locally defined reflection
Highest available central reflection value Rr (max) - 50%
Custom design (substrate shape, wedge, AR coating) available

In order to have better beam quality, i.e. in non-stable resonators, variable reflection mirrors - variable reflectivity mirrors can be used. High intensity of the laser beam requires use of components with a high damage threshold. Dielectric coatings are best suited to meet these requirements. Standa offers variable reflectivity mirrors with dielectric coating, designed at wavelengths in a range from 266 to 2500 nm.
