Broadband Dielectric Mirrors


    The broadband dielectric mirror with optical glass sheet as substrate, uses the surface plating medium to eliminate the polarization film. So that it reflects the 45 degrees incident light at a fixed value. Because the absorption of broadband dielectric mirror is very small, so it can be used in high-energy laser system. Compared with metal film, it has many advantages. For example, its properties are barely degraded over time, durable, easy to clean, and so on.

    Creator Optics ( CNCO ) can produce various customized broadband dielectric mirrors. The main materials are BK7, fused silica, sapphire, BOROFLOAT, Pyrex and so on.


The specifications of broadband dielectric mirrors are as follows:
