In laser applications, the dichroic mirror must be made to much more exacting specifications: less than 1/2 wave per inch surface flatness before coating, less than 1/4 wave transmitted wavefront ...
A protective thin film is applied over these coatings. Dichroic reflector mirrors can reflect greater than 99% over a somewhat narrower spectral region. They are produced with various layers of ...
In a dichroic beamsplitter the light is either reflected or transmitted based on wavelength. By varying the coating on a ...
