MidOpt PR1000 Linear Polarizing Filter
The PR1000 VIS/SWIR Wire Grid Linear Polarizer Mounted Filter is effective in both the visible and NIR (near-infrared), ranging from 400-2000nm. It’s efficient in glare reduction, with an average contrast ratio up to 8,000:1 and has an operating temperature rating of 100° C per 1,000 hours. To maximize glare reduction, use the PR1000 in combination with the PS1000 NIR Linear Polarizer Film over the illuminating light source.
The PR1000 also has an anti-reflection oleophobic coating to maximize transmission while repelling dirt and oil–making it the perfect polarizer for industrial imaging.

About Midwest Optical Systems Polarizers:
Polarizers are designed to reduce specular glare by passing only the light polarized in the direction perpendicular to the reflected light (glare). In addition, they help improve contrast, increase color saturation and detect imperfections in transparent materials. MidOpt Polarizing Filters can be easily and securely mounted to your lens and light source for maximum extinction or glare reduction.
- Contrast ratios average up to 10,000:1
- Linear, circular and wire grid polarizers are available for visible (VIS) and near-infrared (NIR) spectrums
- Rotating mount with locking thumb screw to fine tune glare reduction
- Exceptional surface quality; 40/20 scratch/dig
Polarizing Filter & Film Applications:
Polarizers are commonly used to reduce glare from non-metallic in objects with smooth surfaces or surfaces covered with grease, oil or liquid. For best results, use an optical-grade Polarizer over the lens and Polarizing Film over the light source. The PR120/PG120 offers ultra-high contrast and an anti-reflection oleophobic coating.
For Best Results: Polarizing Film should be used over the light source in conjunction with a Polarizing Filter over the camera lens.
