89-781 57 mm Dia. Mounted Cyan Machine Vision Imaging Filter; t=1.75 mm 518nm

The 89-781 is a 57 mm diameter Cyan Bandpass Filter, specifically designed for machine vision imaging applications. Sourced from Edmund Optics, this filter features a 1.75 mm thickness and a catalog number of 89-781. The filter is made from UVFS Mal-1965 material, ensuring durability and high-quality performance.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths. The Cyan Bandpass Filter has a central wavelength (CWL) of 518nm, with a cut-on wavelength of 470.5nm and a cut-off wavelength of 565.5nm. This specificity in wavelength allows for precise imaging in machine vision applications.

The filter is coated with EDM 89-773 on both the front and back, providing additional protection and enhancing its performance. The shape of the filter is thin lens, making it suitable for a wide range of applications.

The 89-781 filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. For more information or to make a purchase, users can visit the provided weblink.
