The 67-900 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by a 50 mm diameter and a thickness of 5.9 mm, making it suitable for a wide range of applications. The filter's primary function is to allow light transmission within a specific wavelength range, while blocking out unwanted wavelengths.
The 67-900 filter is designed to operate at a central wavelength (CWL) of 560 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity makes it ideal for applications that require precise wavelength selection. The filter's cut-on wavelength is 555 nm, and the cut-off wavelength is 565 nm, 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 and durability, ensuring reliable operation in various conditions. The filter's shape is that of a thin lens, further expanding its potential applications.
