940nm Dielectric Coating Narrow Bandpass Filter
Product Description:
The band pass filter produced by NMOT adopt All-Dielectric hard coating technology and dielectric interference theory. On the basis of highlighting the characteristics of narrow band filter, the optical performance is independent of the thickness of substrate which is easier to build-in instrument imaging system. The optical properties been improved and effectively applied. Special optical material substrate is adopted to solve the problems such as foggy and unstable optical properties of the traditional absorptive synthetic glass.The products are manufactured according to customers' requirements.
