67-806 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 248nm
The 67-806 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use at a central wavelength of 248nm, with a full width at half maximum (FWHM) of 10nm. The filter is mounted, providing a convenient and ready-to-use solution for various optical applications.
The filter's geometry includes a diameter of 25mm and a thickness of 3.5mm, making it suitable for use in systems with specific spatial requirements. The cut-on wavelength is 243nm, and the cut-off wavelength is 253nm, providing a narrow band of transmission.
The 67-806 filter features a traditional coating on both the front and back surfaces, identified as EDM 67-739. This coating enhances the filter's performance and durability, ensuring reliable operation in its intended application.
The filter's shape is described as a thin lens, indicating its potential use in systems where optical power is required in addition to wavelength selectivity. This filter is currently in stock and available for purchase through the provided web link.
