11-981 25 mm Dia. First Surface UV Bandpass Filter; t=1.5 mm 193nm
The 11-981 is a 25 mm diameter First Surface UV Bandpass Filter, with a thickness of 1.5 mm, specifically designed for use at the 193nm wavelength. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
This filter is a Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking other wavelengths. The 11-981 is designed with a cut-on wavelength of 185.5nm and a cut-off wavelength of 200.5nm, making it ideal for applications that require narrow-band UV light. The central wavelength (CWL) of this filter is 193nm, which is the wavelength at which it is most transmissive.
The 11-981 filter is made from UVFS Mal- 1965, a material specifically chosen for its optical properties in the UV spectrum. It features a Thin Lens shape and comes with coatings on both the front and back surfaces, identified as EDM 11-981. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation in its intended application.
