Features

400-700 nm Visible Linear Polarizers

Our unmounted linear polarizing glass filters LPGF-1 and LPGF-2 are recommended for 400-700 nm wavelength applications and are offered in 1 or 2 inch diameter substrates.

750-850 nm NIR Linear Polarizers

We offer unmounted NIR linear polarizer LPNIR-1 for 750-850 nm wavelength applications. The 25 mm diameter B270 Grade substrate has a narrowband multi-layer AR coating on both sides.

1000-2000 nm NIR Linear Polarizers

We offer unmounted NIR linear polarizer LPNIR-2 for 1000-2000 nm wavelength applications.  

Beam Attenuation Using Polarization

A crossed polarizer optical setup can be used to easily control beam attenuation by rotating a second polarizer in the optical path. In this setup, a HeNe laser beam passes through a polarizing beamsplitter cube, separating the light into two orthogonal linear polarizations. A polarizer on a rotation mount is placed after the beamsplitter. Rotation of the second polarizer illustrates how the intensity of transmitted light varies with polarization angle. This demonstration highlights how light can be manipulated and attenuated for different optical systems by using polarization. Proper safety precautions should be followed, and beam blocks or barriers should be used to safely terminate stray beams. See the parts list of the shown setup example.
