65-663 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 780nm

The 65-663 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 is designed to operate at a central wavelength of 780 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity makes it ideal for applications that require a narrow bandwidth, such as fluorescence microscopy or laser spectroscopy. The cut-on wavelength is 775 nm, and the cut-off wavelength is 785 nm, ensuring a high level of transmission within the passband and a sharp roll-off outside of it.

The 65-663 filter features a thin lens shape, which can be beneficial in applications where space is limited or precise alignment is required. The front and back surfaces of the filter are coated with the EDM 65-663 coating, which is specifically designed to enhance the performance of the filter.

This filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. The catalog number for this filter is 65-663, and it is part of the UVFS MAL-1965 material ID.
