The 65-666 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 is designed to operate at a central wavelength (CWL) of 852 nm, with a full width at half maximum (FWHM) of 10 nm. The cut-on wavelength is 847 nm, and the cut-off wavelength is 857 nm, providing a narrow bandwidth that can help to reduce unwanted noise and improve signal-to-noise ratios in many optical systems.
The 65-666 filter features a thin lens shape, which can help to minimize optical aberrations and improve image quality. The front and back surfaces of the filter are coated with the EDM 65-666 coating, which is specifically designed to enhance the performance of the filter in its intended application.
