Pair of LINEAR polarization filters in rigid plastic 45 degrees, -45 degrees. Size 7.6 x 7.6 cm. Ideal for any pair of standard lens projectors, they work with linear polarization passive 3D glasses. No mounting and positioning system is included.
It is recommended to be careful not to place these filters too close to the projector lens, as excessive heat can damage them irreparably (event not included in the warranty).
It is important that the light beam covers as much as possible the entire surface of the filter to avoid heat concentrations in specific points. Optional additional glasses are available to absorb heat and preserve the life of the polarized filter.
