UV Filter


He Rui optics' UV filters, or ultraviolet filters, are specialized optical elements designed to extract specific wavelengths of ultraviolet light. They work based on the selective absorption and transmission properties of different wavelengths of light, typically designed to allow only a certain range of ultraviolet wavelengths to pass through while blocking other wavelengths such as visible or infrared light. This selective filtering characteristic makes UV filters useful in various fields, including research, medical, and industrial applications.

UV filters can be categorized into various types based on application needs, such as:

  • UV bandpass filters: Allow a specific band of ultraviolet light to pass through while blocking other wavelengths.

  • UV low-pass filters: Primarily allow low-band ultraviolet light to pass through while blocking high-band light.

  • UV high-pass filters: Primarily allow high-band ultraviolet light to pass through while blocking low-band light.
