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:
NEW IR-Block/Visible Transmitting Optical Filters
Palatine, Ill. (January 19, 2017) – MidOpt announces the availability of three new imaging filters primarily intended for blocking unwanted near-infrared light. Filters include: SP635 Absorptive Visible Shortpass/Near-IR Block Filter, SP644 Near-IR/Mid-Red Dichroic Block Shortpass Filter, and AB555 Acrylic Absorptive Near-IR/UV-Block Visible Bandpass Filter.
“Mounting solutions are also available to help customize any imaging application,” says MidOpt Founder Barry Warzak. MidOpt’s unique filter mounting options include: Standard Threaded Mounts, Slip Mounts that easily adapt to lenses without filter threads, the exclusive 25.4™ C-Mount for easy installation into cameras, and custom fabrication of unmounted shapes and sizes.
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.
