Broadband Dielectric Mirrors

Broadband Dielectric Coating in visible range

   Broadband dielectric mirrors are general-purpose components useful in a wide variety of applications. Photometric response is better than 95% weighted reflectance at both normal and 45° incidence, in either polarization. High reflectivity is also provided at most common laser and LED wavelengths. Because these mirrors are composed of multi-stack e-beam dielectric materials, physical durability is excelllent, and optical response is retained for years, in contrast to the gradual degradation seen in even the best protected aluminum mirrors. The standard substrate material is BK7, although other materials can be supplied.
