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.
Polarizers are commonly used to reduce glare from objects with smooth surfaces or surfaces covered with grease, oil or liquid. Polarizers can also be used to detect stress and imperfections in transparent material.
Before: Reflected glare from shiny, curved surfaces affect the performance of the camera's auto-gain feature and interferes with reliable pattern detection.
After: Linear Polarizing Filters on the lens and light source, carefully aligned for maximum glare extinction, eliminate specular reflections off of the offending part, narrowing the dynamic range.
