67-908 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 740nm
The 67-908 is a Bandpass Filter with a circular base shape and a 50 mm mounted diameter, sourced from the reputable vendor Edmund Optics. This filter is designed to transmit light within a specific range of wavelengths while blocking other wavelengths, making it ideal for applications that require narrowband light transmission.
The filter's primary wavelength is 740 nm, with a full width at half maximum (FWHM) of 10 nm. The FWHM is a measure of the filter's bandwidth, indicating the range of wavelengths that the filter allows to pass. The cut-on wavelength is 735 nm, and the cut-off wavelength is 745 nm, further defining the filter's passband.
The filter is constructed with a thickness of 5.9 mm and is made from UVFS Mal-1965 material. The front and back surfaces of the filter are coated with EDM 67-774, a traditional coating that enhances the filter's performance and durability.
The filter's geometry includes a diameter of 50 mm, making it suitable for use in various optical systems. The shape of the filter is thin lens, which is beneficial for applications that require minimal optical path length distortion.
The 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, users are encouraged to visit the provided weblink.
