Abstract

A durable Interference Filter for 1.65 (mu) with peak transmittance of above 90% is shown. The filter consists of Si and SiO₂ layers on glass, with a SiO₂ top layer for additional durability. Applying on the other side of the substrate an edge filter (long wave pass filter) with the same materials, resulted with a large blocking spectral region, without the use of an absorbing glass substrate.
