65-666 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 852nm
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.
This filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
