67-881 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 289nm
The 67-881 is a 50 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically coated to allow transmission in the ultraviolet (UV) range, with a central wavelength (CWL) of 289nm and a full width at half maximum (FWHM) of 10nm.
The filter is constructed with a thickness of 3.5mm, providing durability and stability. It is cut on at 284nm and cut off at 294nm, ensuring a narrow bandwidth transmission. The filter is mounted, making it ready for immediate use in optical systems.
The coating on both the front and back of the filter is EDM 67-747, a traditional coating developed by Edmund Optics. This coating enhances the filter's performance in the UV range, providing high transmission and excellent blocking of unwanted wavelengths.
The filter's geometry is in the shape of a thin lens, allowing it to be easily integrated into various optical systems. The catalog number for this filter is 67-881, and it is currently in stock on the Edmund Optics website, as indicated by its weblink status.
