BP395nm bandwidth 20nm bandpass filter

RUICCN-BP395nm bandpassoptical filterIt is applied in the ultraviolet and purple bandsBandpass filterThis product is coated with JGS1 quartz material, allowing light with a wavelength of 350nm and a bandwidth of 70nm to pass through. It cuts off deep ultraviolet, visible, and near-infrared light outside the passband. If you have any additional requirements for substrate materials, please contact our customer service personnel.

The 395nm bandpass filter produced by Ruicheng Optoelectronics is characterized by the controlled steepness from the cutoff point to the high transmittance point, and the designed cutoff range is also relatively wide. However, for the production process of ultraviolet bandpass filters and the actual difficulty of film systems, there are not many domestic manufacturers that can cutoff up to 1100nm. This product has achieved a very high cutoff from 200nm deep ultraviolet to 4000-700nm visible light and 780-1100nm near-infrared light.
