MidOpt PC052 Linear Polarizing Filter
Used to eliminate specular reflections and hot spots, Circular Polarizers in rotating mounts allow maximum flexibility and ease of use. However in most machine vision applications we recommend the use of linear rather than circular polarizers. Circular polarizers are recommended for eliminating glare from spherical surfaces or in cases where an auto-focus or metering system are used involving a beamsplitter or mirror mounted in the optical path inside the camera.
Best results are achieved when circular polarizing film is also used over the light source. Left-handed and right-handed polarization directions are available.
*Not available in 1mm thickness or standard 25.4™ C-Mount option. For filters thicker than 1mm, we offer an alternative mounting solution that has an overall thickness of 5.5mm. This mount can accommodate filters up to 3.5mm thick. To view this alternative C-Mount option, click here.

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.

MidOpt Filter Mounting Options
Midwest Optical Systems offers filters in the following standard mounts. Most filters have both male and female threads to enable the ability to stack filters. For specific questions, please contact Machine Vision Direct.
- Designed for lenses with filter threads, a variety of filter types and stock threaded sizes are available: M13.25-M105
- Larger sizes, 62mm to 105mm, are made to order and are not returnable
- Custom thread sizes are available upon request
- Black anodized aluminum rings
- Rotating mounts with locking thumb screws are available upon request and come standard with Polarizing Filters
How to Order
To order a filter with a threaded mount, first select a filter (e.g. BP470) and add the mount size (e.g. M27) to build your part number (e.g. BP470-27). For help building your filter part number, visit an individual filter page.
