65-787 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 1250nm
The 65-787 is a 25 mm diameter mounted bandpass interference filter, specifically designed for applications requiring a center wavelength of 1250nm. This filter, offered by Edmund Optics, boasts a full width at half maximum (FWHM) of 10nm, making it an ideal choice for applications demanding high spectral resolution. The filter's thin lens shape, with a thickness of 7.5mm, ensures minimal optical path differences and reduces the risk of unwanted reflections.
The 65-787 filter is cut on at 1245nm and cut off at 1255nm, providing a narrow, precise bandpass. This characteristic is particularly beneficial in applications such as fluorescence microscopy, spectroscopy, and optical telecommunications, where precise wavelength selection is crucial.
The filter is coated with EDM 65-773 on both the front and back surfaces, enhancing its performance and durability. This coating provides excellent environmental stability, making the filter suitable for use in various conditions.
