67-783 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 820nm
The 67-783 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its circular shape, with a diameter of 12.5 mm, 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 of 820 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity makes it ideal for applications that require narrowband filtering around the 820 nm wavelength. The filter's cut-on wavelength is 815 nm, and the cut-off wavelength is 825 nm, further enhancing its ability to isolate the desired wavelength.
The 67-783 filter features a thin lens shape, which is beneficial in applications where space is a constraint. The front and back surfaces of the filter are coated with the EDM 67-783 coating, which enhances its performance and durability.
