Linear polarizer for laser power regulation

Linear Polarizer or Linear Polarizer Filter 

Dimensions: 26mm x 28mm 

Polarization axis: 45 degrees (standard for 3d projection).  

Specially designed for the regulation of laser power: 

The use of 2 linear polarizers allows the regulation of output power of the lasers.

The regulation of the intensity of light is obtained by the optical assembly of 2 linear polarizers at the light output. The relative rotation of the polarizers will change the intensity of the light. 

In the case of having a laser with linearly polarized light output, it is only necessary to use a linear polarizer.
