Optical Coating Glass 940nm Bandpass Filter for Red LIght Shielding
Product Description:
The bandpass filter produced by NMOT adopts dielectric hard-film coating technology and the principle of dielectric interference.
On the basis of highlighting the characteristics of narrowband filter, its optical performance is independent of the thickness of the substrate, which make it more convenient to be built into the instrument imaging system, improve the optical performance and realize effective application.
The use of special optical material substrate has solved the problems of fog prone and optical performance instability of traditional absorbent synthetic glass. The product can be produced according to the customer's index requirements.
