Product introduction：

The so-called narrow band filter, bandpass filter from the subdivision out in its definition, with the same band pass filter, it is this filter allows the optical signals in a specific region by, and deviate from the sides of the band other than the light signal is blocked, narrowband filter pass band is relatively narrow, generally as the center wavelengths 5% the following.

Narrowband filter main role is to make the specific wavelengths of light by reflection, let the other wavelengths of light (or decay) optical elements. Half wave width usually controlled to 20nm or less, ultraviolet, visible, near infrared wavelength, far infrared band. Narrow band filter of our company adopts a multi-layer dural by ion assisted deposition of nano material of high vacuum evaporation and film, good compactness, high imaging definition.

Product advantages：
