This 200 x 200 x 0.3mm Polarizing Film for Lighting from B+W can be positioned over an LED light source or flash system. Due to the amount of the heat generated, it may also be used with repro lamps to a limited extent. The polarizing film is useful for preventing reflections or glare from occurring in an image or scene as output from a light source interacts with reflective materials around it. When placed between a light source and a transparent or translucent object, the polarizing film can help show the object's photoelasticity.
