Product Description: Half-wave width is usually controlled at 20nm or smaller, ultraviolet, visible, near-infrared wavelengths, far-infrared wavelengths. Our narrow-band filters using multi subdural by ion assisted deposition of nano-materials made of high-vacuum evaporation, coating good compactness, high-resolution imaging. Change the direction of propagation of the light, and can change the ultraviolet, visible or infrared glass relative spectral distribution of light. Refers to a narrow optical glass colorless optical glass; generalized optical glass further comprising colored optical glass, laser glass, optical glass, glass anti-radiation, ultraviolet infrared optical glass, optical glass fiber, sound and light glass, the magneto-optical and optical glass. Optical glass can be used in the manufacture of optical instruments lens, prisms, mirrors and windows. Member made of an optical glass is an optical instrument key element.
Narrowband filter main role is to make a specific wavelength of light through, so that reflects other wavelengths of light (or attenuation) of the optical element.
