The 67-919 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 requiring wavelength selectivity.
The filter's primary wavelength is 850 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 effectively transmit around the central wavelength. In this case, the 67-919 can transmit wavelengths from approximately 845 nm to 855 nm.
The 67-919 features a thickness of 5.9 mm and is constructed from UVFS Mal-1965 material. The filter's front and back surfaces are coated with EDM 67-785, a traditional coating that enhances its performance and durability.
This filter is designed in a Thin Lens shape, which is advantageous in applications where space is a constraint.
