The 14-923 is a 50 mm diameter First Surface UV Bandpass Filter, with a thickness of 1.5 mm, specifically designed for use with a central wavelength of 265nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
As a Bandpass Filter, the 14-923 allows light to pass through a specific range of wavelengths, while blocking out other wavelengths. In this case, the cut-on wavelength is 260nm, and the cut-off wavelength is 270nm, making it ideal for applications that require a narrow band of ultraviolet light.
The filter is made from UVFS Mal-1965 material, and features a Thin Lens shape. The front and back of the filter are coated with EDM 11-993, a coating that enhances the filter's performance and durability.
