The 14-922 is a 50 mm diameter First Surface UV Bandpass Filter, with a thickness of 1.5 mm, specifically designed for use at a central wavelength of 260nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock.
The filter is a Bandpass type, which means it allows light to pass through within a specific range of wavelengths while blocking other wavelengths. In this case, the 14-922 is designed to cut on at 255nm and cut off at 265nm, making it ideal for applications that require narrow-band UV light.
The filter is made from UVFS Mal-1965 material, and both the front and back surfaces are coated with EDM 11-992 for optimal performance. The filter's shape is that of a Thin Lens, which can be beneficial in certain optical system configurations.
