67-791 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 900nm
The 67-791 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter features a circular shape with a 12.5 mm diameter and a thickness of 5.9 mm, making it suitable for a wide range of optical applications.
The filter is designed to operate at a central wavelength (CWL) of 900 nm, with a full width at half maximum (FWHM) of 40 nm. This specificity makes it ideal for applications that require narrowband filtering around the 900 nm wavelength. The filter's cut-on wavelength is 880 nm, and the cut-off wavelength is 920 nm, further enhancing its ability to isolate specific wavelengths.
The 67-791 filter is coated on both the front and back sides with EDM 67-791, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation.
The filter is mounted, making it easy to integrate into existing optical systems. It has a thin lens shape, which contributes to its versatility and ease of use. The filter's catalog number is 67-791, and it is currently in stock, according to the vendor's website.
