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.
The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its precise specifications and reliable performance, the 65-660 is an excellent choice for those seeking a high-quality bandpass interference filter.
