Polarizing Film
Film to reduce reflections and increase contrast
Looking for high performance polarizing films? Our polarizing films reliably reduce reflections. At the same time, high contrast is maintained and image quality is not compromised.
Polarizing film for the industry
Polarizing films from Schneider-Kreuznach are used wherever interfering reflections need to be reduced. Our films offer high contrast and broad spectral transmission. In addition, our optical solutions have been specially developed for use in industrial environments and under demanding conditions. Schneider-Kreuznach supplies both glass polarizers for lenses and polarizing films for lighting solutions.
What is the function of a polarizing films?
A polarizing filter, also called a polarizer, consists of a polarizing film that allows partially polarized light to pass through. This eliminates reflections and increases contrast.
Where is polarizing films used?
In industry, polarizing filters are used in a variety of applications where polarized light is critical. For example, in imaging applications such as microscopy, polarizer filters are used to improve contrast and image quality by selectively blocking or transmitting polarized light waves. They are also used in LCD displays to control the polarization of light passing through the liquid crystal cells, enabling the production of high-quality, high-contrast displays.
KEY FEATURES OF OUR Polarizing FILm
- Reduce reflections: Minimize unwanted glare and reflections for clearer images.
- Increase contrast: Enhance the distinction between different elements in an image.
- High extinction ratio: Efficiently block unwanted light to achieve optimal polarization effects.
- Pre-cut custom shapes for polarizing films on request: Tailor-made polarizer shapes for specific applications available upon request.

Polarizer - Polarizing film
The P-W 76 and P-W 64 polarizing films feature a high contrast (erasure) of 10,000:1 (P-W 76) and 40,000:1 (P-W 64), respectively. These films can be used to reduce interfering reflections in the visible range of 430 nm to 780 nm from reflective surfaces or to make stress patterns visible on transparent plastics. They are also used to enhance the contrast of images. The films can be cut into any shape using a laser cutter.
Environmental Facts of the polarizing film
Our industrial optical polarizer films are tested to DIN standards to ensure they meet stringent environmental requirements. These tests check the durability of the polarizer films, their resistance to temperature changes and their ability to withstand exposure to harsh chemicals and other environmental stressors. This ensures that the polarizer films are up to the task in demanding industrial applications, providing consistent performance and reliability over time.
