Lee Filters Polarisation material 12"x19" - Unframed sheet can be clipped to lights. Useful for reducing reflection while copying original artwork.

LEE neutralising linear polarising film is used in front of lights to reduce the glare caused by smooth surfaces such as glass, water, paper and certain metallic objects.

Each filter is clearly marked to indicate the axis of polarisation.

This sheet is especially effective when used in conjunction with a polarising filter at the lens (cross polarisation). It should be placed at a slight distance from hot lights.

Most objects produce some glare. Even though it may be minor, this glare can cause a "washing out" or weakening of the object's colour. "Cross polarisation" can reduce this glare to provide richer colour saturation. Transmission is 38% (1 1/2 stops).

This neutral grey linear polarising film is used in front of lights to reduce the glare caused by smooth surfaces such as glass, water, paper and certain metallic objects. Especially effective when used in conjunction with a polarizing filter at the lens (cross polarization). It should be placed at a distance from hot lights.

In addition to glare reduction, Lee Polarising Filters may be utilized for a variety of other special effects or technical applications. These include Birefringence (for crystal photography) and motion illusion. Polarising Filter is produced on as mil acetate base. It is an excellent neutral grey with minimal colour temperature shift.

Implementing polarisation control can be useful in imaging applications.
By placing a linear polariser over the light source, the lens, or both, it is possible to eliminate glare and hot spots from reflective objects or bring out surface defects.

Material stress can be quantified in transparent objects using the photoelastic effect. Stressed material becomes birefringent, and the stress and its related birefringence can be measured by using polarised light.

Polarisation is also very important in the chemical, pharmaceutical, and food and beverage industries.
