Product features:
Narrow band filter is a major role in light of a specific wavelength through, let the other wavelengths of the light reflection ( or attenuation) of optical components. Half wave width is usually controlled in 20nm or smaller, ultraviolet, visible light, near infrared wavelength, far infrared wave band . My company's narrow bandpass filter using multilayer epidural by ion assisted deposition of nanometer materials and high vacuum evaporation coating, good compactness, high imaging definition.
Optical indicator:
The center wavelength: 940 ± 7Nm
Transmittance: T>80%
Bandwidth: 20nm
Band 350-910nm
1000-1100nm
The cutoff rate: T<0.1%
