The 67-769 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's primary function is to allow light within a specific wavelength range to pass through while blocking light outside this range. In this case, the central wavelength (CWL) is 660nm, with a full width at half maximum (FWHM) of 10nm. The cut-on wavelength is 655nm, and the cut-off wavelength is 665nm, indicating a narrow and precise wavelength transmission.
The 67-769 filter features a coating on both the front and back surfaces, identified as 'edm 67-769'. This coating enhances the filter's performance and durability, ensuring optimal functionality in its intended application.
The filter's geometry and physical data suggest that it is a thin lens, ideal for applications where space is a constraint. The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
