11-997 25 mm Dia. First Surface UV Bandpass Filter; t=1.5 mm 313nm
The 11-997 is a 25 mm diameter First Surface UV Bandpass Filter, with a thickness of 1.5 mm, specifically designed for use at the 313nm wavelength. This filter is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The filter is a Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking other wavelengths. In this case, the 11-997 is designed to pass light between 308nm and 318nm, with a central wavelength (CWL) of 313nm. This makes it ideal for applications that require precise filtering in the ultraviolet spectrum.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties in the UV range. It features a Thin Lens shape, which is designed to minimize optical aberrations and distortions, ensuring the highest quality light transmission.
The front and back surfaces of the filter are coated with EDM 11-997, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance, providing improved durability and resistance to environmental factors.
