Band-pass optical filter

broadband

Wide bandpass filters are designed to isolate a wide spectral band and exhibit high peak transmission in the passband. TypicallyT>80% average. Available wavelengths are 1um – 15um. Transmission >85% Attenuation <0.1% outside passband Edge Slopes 3%-5% typically Environmental Properties Adhesion MIL-C-48497A, 08/09/1980, para 4.5.3.1 Tape test Humidity MIL-C-48497A, 08/09/1980, para 4.5.3.2 24hrs, 48°, 95% relative humidity Abrasion MIL-C-48497A, 08/09/1980, para 4.5.3.3 Moderate, 50 strokes with a cheesecloth
