89-842 65 mm Dia. Mounted IR Machine Vision Imaging Filter; t=1.75 mm 880nm
The 89-842 is a circular filter, 65 mm in diameter and 1.75 mm thick, designed for machine vision applications in the infrared spectrum. This filter, offered by Edmund Optics, is a bandpass filter, which means it allows light to pass through within a specific range of wavelengths while blocking other wavelengths.
The filter's primary wavelength (CWL) is 880nm, making it ideal for applications that require precise filtering in this range. The cut-on wavelength is 812.5nm, and the cut-off wavelength is 947.5nm, indicating the range within which the filter is most effective.
The 89-842 filter features a coating on both the front and back surfaces, specifically the EDM 89-834 coating. This coating enhances the filter's performance and durability, ensuring optimal results in your machine vision applications.
The filter's shape is described as "Thin Lens," suggesting it may have lens-like properties or be designed to be used in conjunction with lenses. This filter is currently in stock and available for purchase through the provided weblink.
