Технические характеристики

The film of narrowband filter is generally composed of two kinds of films with low refractive index and high refractive index. After superposition, the number of layers can reach dozens of layers. The parameters of each layer of film may affect the final performance.

The transmittance of narrowband filter is very sensitive to the loss of thin film, so the production process is relatively high.The narrowband filters are mainly used in the applications of medical biochemical instrument, ELIASA, pesticide residue detection, water quality analysis system and variety of detecting instruments.

Features

High wavelength positioning accuracy

Hard and firm coating film

Good heat resistance and moisture resistance

Long service life(over 5 years under general condition)
