65-662 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 766nm
The 65-662 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 (CWL) of 766 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 761 nm, and the cut-off wavelength is 771 nm, ensuring a high level of transmission within the specified bandwidth and a sharp roll-off outside of it.
The 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 65-662 coating, which is specifically designed to enhance the performance of the filter.
The 65-662 is currently in stock and available for purchase through the Edmund Optics website. The catalog number for this item is 65-662, and it can be found at https://www.edmundoptics.com/p/766nm-cwl-10nm-fwhm-125mm-mounted-diameter/20180/.
