65-660 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 694nm

The 65-660 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 694nm, with a full width at half maximum (FWHM) of 10nm. The cut-on wavelength is 689nm, and the cut-off wavelength is 699nm, providing a narrow and precise bandwidth for light transmission.

The 65-660 filter features a unique coating on both the front and back surfaces. This coating, identified as EDM 65-660, is designed to enhance the filter's performance and durability. The filter's shape is that of a thin lens, further expanding its potential applications in various optical systems.
