Bandpass Filter

        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      


All filters are available in 12.7, 25.4, and 50.8mm diameters, or requested dimension.


Common Specifications:

· Transmission (%): >90

· Surface Quality: 40-20

· Optical Density OD: >4.0

· Substrate: H-K9L, Fused Silica or requested
