The 65-647 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 out other wavelengths. In this case, the central wavelength (CWL) is 589nm, with a full width at half maximum (FWHM) of 10nm. The cut-on wavelength is 584nm, and the cut-off wavelength is 594nm, indicating a narrow and precise wavelength transmission.
The 65-647 filter features a unique coating on both the front and back surfaces. This coating, identified as 'edm 65-647', 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.
