67-928 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 930nm
The 67-928 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 930 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 it can transmit around the central wavelength. In this case, the 10 nm FWHM means the filter can transmit light between 925 nm and 935 nm.
The filter is made from UVFS Mal-1965 material and has a thickness of 5.9 mm. It features thin lens geometry, which is beneficial for applications that require minimal optical path differences. The filter's front and back are coated with EDM 67-794, a coating type known for its durability and excellent optical properties.
The 67-928 is currently in stock and available for purchase through the Edmund Optics website. The provided weblink leads directly to the product page for easy access and ordering.
