A dark-colored glass filter used to isolate ultraviolet light.
The "UV Transmission and Visible Absorption Filter" is a dark-colored filter glass that transmits ultraviolet light, absorbs visible light, and slightly transmits near-infrared light. The numbers associated with the glass type represent the wavelengths at which the maximum transmission rate occurs. It is primarily used to isolate ultraviolet light and is utilized to selectively transmit wavelengths of 253.7 nm and 365 nm, which are representative spectral lines of mercury lamps. 【Features】 ■ Transmits ultraviolet light and absorbs visible light ■ Slightly transmits near-infrared light ■ Used when isolating only ultraviolet light ■ Utilized to selectively transmit wavelengths of 253.7 nm and 365 nm *For more details, please refer to the PDF document or feel free to contact us.
