Machine Vision Filters are Optical Filters designed to improve the image quality and contrast in imaging or other machine vision applications. Machine Vision Filters are available in a variety of convenient mounted options to ease integration onto Imaging Lenses. Machine Vision Filters can be used to increase or decrease color temperature, block unwanted ultraviolet or infrared light, reduce overall light transmittance, or transmit light of a specific polarization state.

Edmund Optics offers a wide variety of Machine Vision Filters for integration into a range of applications such as inspection, robotics, or factory automation. Shortpass Optical Filters remove red or NIR light, while Longpass Optical Filters remove violet or blue light. Neutral Density (ND) Filters can be stacked to increase optical density, decreasing overall light throughput. Color Filters are ideal for use with black and white (monochrome) cameras to increase contrast and resolution. Empty mounts are available to integrate Edmund Optics’ full line of filters into machine vision applications.
