Bandpass filters are optical elements that are designed to transmit a specific spectral band with high efficiency, while reject others. The characteristics of the bandpass are controlled by multilayer dielectric coatings

Substrate: commercial quality window or precision window. Please refer to the optical window page.

Typical applications:

1. Nd: Laser application:

A)R>99.8% @1064nm & R<5%@532nm                                 B)R>99.8%@532nm & R<5%@1064nm

 2. Telecommunication applicaiton:
