65-656 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 656nm
The 65-656 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 7.5 mm, making it suitable for a wide range of optical applications.
The filter's primary function is to allow light within a specific wavelength range to pass through while blocking light outside this range. The central wavelength (CWL) of this filter is 656 nm, with a full width at half maximum (FWHM) of 10 nm. The cut-on wavelength is 651 nm, and the cut-off wavelength is 661 nm, providing a narrow and precise bandpass.
The 65-656 filter features a thin lens shape and is made from UVFS material, specifically identified as MAL-1965. It is coated on both the front and back surfaces with the EDM 65-656 coating, enhancing its performance and durability.
