89-811 57 mm Dia. Mounted Orange Machine Vision Imaging Filter; t=1.75 mm 590nm

The 89-811 is a mounted orange bandpass filter, specifically designed for machine vision imaging applications. Sourced from Edmund Optics, this filter boasts a catalog number of 89-811 and is readily available for purchase. The filter is characterized by its circular shape and thin lens design, making it an ideal choice for various optical systems.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths. In this case, the 89-811 filter is designed to pass light with a central wavelength (CWL) of 590nm. The cut-on wavelength is 550.5nm, and the cut-off wavelength is 629.5nm, providing a relatively narrow passband. This characteristic makes it particularly suitable for applications that require precise wavelength selection.

The filter is made from UVFS MAL-1965 material, a common choice for optical filters due to its excellent optical properties. It has a diameter of 57mm and a thickness of 1.75mm, ensuring durability and stability in its mounting. The front and back surfaces of the filter are coated with EDM 89-803, a coating that enhances the filter's performance and longevity.
