BP380nm bandwidth 20nm bandpass filter

RUICCN-BP380nm bandpassoptical filterIt is applied in the ultraviolet and purple bandsBandpass filterThis product is coated with JGS1 quartz material, allowing light with a wavelength of 380nm 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 additional requirements for substrate materials, please contact our customer service personnel.

The 380nm bandpass filter produced by Ruicheng Optoelectronics is characterized by a very steep control from the cut-off point to the high transmittance point, and a relatively wide cut-off range design. However, for the production process and film system of ultraviolet bandpass filters, there are not many domestic manufacturers that can cut-off 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.
