67-779 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 790nm
The 67-779 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 5.9 mm, making it suitable for a wide range of optical applications.
The filter is designed to operate at a central wavelength (CWL) of 790 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 785 nm, and the cut-off wavelength is 795 nm, ensuring a high level of transmission within the passband and a sharp roll-off outside of it.
The 67-779 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 67-779 coating, which provides excellent optical performance and durability.
This filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. For more detailed information or to place an order, users are encouraged to visit the provided weblink.
