67-774 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 740nm
The 67-774 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 740 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 735 nm, and the cut-off wavelength is 745 nm, ensuring a high level of transmission within the specified bandwidth and a sharp roll-off outside of it.
The 67-774 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 67-774 coating, which is specifically designed to enhance the performance of the filter.
