The 67-833 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its 25 mm diameter and 5.9 mm thickness, making it suitable for a wide range of applications. The filter's primary function is to allow light in a specific wavelength range to pass through while blocking light in other wavelengths, making it an essential component in various optical systems.
The 67-833 filter is designed to operate at a central wavelength (CWL) of 560nm, with a full width at half maximum (FWHM) of 10nm. This specificity makes it ideal for applications that require precise wavelength selection. The filter's cut-on wavelength is 555nm, and the cut-off wavelength is 565nm, further enhancing its wavelength selectivity.
The filter's front and back surfaces are coated with EDM 67-766, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission. The filter's shape is that of a thin lens, which contributes to its compactness and ease of integration into optical systems.
