67-852 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 850nm
The 67-852 is a 25 mm diameter mounted bandpass interference filter, designed for use in optical systems where precise wavelength selection is required. This filter, offered by Edmund Optics, features a center wavelength of 850 nm and a full-width half-maximum (FWHM) of 10 nm, providing a narrow, well-defined passband.
The filter is constructed with a thickness of 5.9 mm and is designed to be mounted, making it easy to integrate into existing optical systems. The front and back surfaces of the filter are coated with EDM 67-785, a proprietary coating developed by Edmund Optics, which enhances the filter's performance and durability.
The 67-852 filter is designed to pass light within the specified wavelength range (845 nm to 855 nm) while blocking light outside this range. This makes it ideal for applications such as fluorescence microscopy, spectroscopy, and other scenarios where specific wavelengths need to be isolated or emphasized.
The filter's circular shape and thin lens design further enhance its versatility, allowing it to be used in a wide range of optical systems. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
