Key Features of a Quality Machine Vision Filter
Optical filters are critical components for machine vision applications. They’re used to maximize contrast, improve color, enhance subject recognition and control the light that’s reflected from the object being inspected. A machine vision filter is not just a machine vision filter. Here’s what to look for when choosing a filter for your machine vision system:
Midwest Optical Systems Announces StablEDGE™
Palatine, Ill. (April 27, 2016) – Midwest Optical Systems (MidOpt) announces the release of a broad range of StablEDGE™ filters. StablEDGE™ is an innovative hybrid filter design that maintains critical spectral performance in imaging applications with short focal length lenses (<12mm) or angular-dependent lighting. In traditional filter designs, as the angle of light reaching the filter changes, the passband exhibits “short shifting,” and image contrast can be significantly degraded. Because the use of shorter vs. longer focal length camera lenses now predominates the market, MidOpt’s StablEDGE™ filter designs surpass those of all major filter suppliers in maintaining a desired width of passband in all applications, transmitting desired LED/laser diode illumination while blocking interfering light.
