      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.
