Bandpass Filters

About Evaporated Coatings Inc.

• Type: Filter Coatings
• Filter Coating - Category: Bandpass

Bandpass low loss optical filters are designed and applied using new and progressive deposition methods. Bandpass optical filters are available for wide sideband blocking applications for maximum performance from 400 to 2000 nm. Typical out-of-band rejection is 0.01% T (OD 4) or better. Filters have high transmission levels with low passband ripple; typical peak passband transmission is > 90%. Excellent environmental stability for demanding military and telecom applications. High performance bandpass filter coatings are deposited on custom optics, crystals, polymers, fibers, semiconductors, and glass substrates up to 200 mm diam.
