67-786 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 850nm
The 67-786 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 850 nm, with a full width at half maximum (FWHM) of 40 nm. This means it allows light within a narrow band around 850 nm to pass through while blocking out other wavelengths, making it ideal for applications that require precise wavelength selection.
The cut-on wavelength is 830 nm, and the cut-off wavelength is 870 nm, further emphasizing its bandpass characteristics. The coating on both the front and back of the filter is EDm 67-786, which is specifically designed to enhance its performance and durability.
The filter is mounted, which adds to its convenience and ease of use. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
