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 band

Points for attention in use:
1 when using please wear finger sets, not a finger directly touch the lens surface, so as to avoid residual finger affect lens optical effect.
2 if the lens surface is dirty, available clean cloth or paper with an alcohol wipe the lens surface. Not available surface is coarse cloth or paper or wet wipe, otherwise it will damage the lens surface.
3 check the light path adjusting the optical axis, please do some protection.
Application areas: narrowband filter is in all kinds of glass surface by a special coating process and the formation of the optical element, can from the incident light wavelength selecting any demand, half peak between 5nm~50nm in general; narrow band filters also can be replaced if the grating as expensive optical devices, widely used in various types of spectral measurement, biochemical analysis apparatus and optical experiments and industrial areas.
