BP400nm bandwidth 20nm bandpass filter

RUICCN-BP400nm bandpassoptical filterIt is applied in the ultraviolet and purple bandsBandpass filterThis product is coated with JGS1 quartz material, allowing light with a wavelength of 400nm and a bandwidth of 20nm to pass through. It cuts off deep ultraviolet, visible, and near-infrared light outside the passband. If you have any other requirements for substrate materials, please contact our customer service personnel.

The 400nm 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 and actual difficulty of the film system of the ultraviolet bandpass filter, 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.
