Polarizing Lens Filters
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
Acrylic Polarizing Filters
Often called "Protective Windows" these longpass filters are also protective. They stand up to tougher environments made from materials like Borofloat or fused silica.
Non-Acrylic Polarizing Filters
Longpass Filters are often used in fluorescence applications to block an excitation light source or to pass multiple emission wavelengths, improving signal to noise ratio. Longpass Filters are also commonly used in photography and astronomy.
