65-692 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 488nm

The 65-692 is a 25 mm diameter Bandpass Interference Filter, specifically designed for use at a central wavelength (CWL) of 488nm. This filter, offered by Edmund Optics, is a crucial component for applications requiring precise wavelength selection and narrow bandwidths.

The filter features a 10nm full-width half-maximum (FWHM), ensuring a tight passband and high spectral purity. The cut-on wavelength is 483nm, and the cut-off wavelength is 493nm, further emphasizing its ability to isolate the desired wavelength.

The 65-692 filter is made from UVFS Mal-1965 material, a common choice for its excellent optical properties and durability. It has a thickness of 7.5mm, providing sufficient mechanical strength while maintaining minimal optical thickness.

Both the front and back surfaces of the filter are coated with EDM 65-632, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving overall system efficiency.

The filter's circular shape and thin lens design ensure easy integration into various optical systems. Its geometry and physical data make it an ideal choice for applications such as fluorescence microscopy, spectroscopy, and laser systems.
