Glan Thompson Polarizers

Glan Thompson polarizer is a polarizing optical element composed of two right-angle prisms. Its advantages are large acceptance angle and high polarization purity. It is widely used in optical experiments, laser systems, optical imaging and spectroscopy. However, due to the use of adhesives, its use in high-power applications is limited.

Advantage:

Large Acceptance Angle: Due to their large aspect ratio, Glan Thompson Optical Polarizers have a large acceptance angle and are suitable for both divergent and focused light sources.
High polarization purity: Capable of providing polarization purity up to 20,000:1.
Wide spectral range: Suitable for applications in a wide spectral range.
Durability: Able to perform well in medium-power applications due to its design and materials.

Applications:

Optical experiments: In experimental setups where high polarization purity and large acceptance angles are required.
Laser Systems: Used in laser systems to improve the polarization properties of light.
Optical imaging: In optical imaging systems, it is used to improve the contrast and clarity of images.
Spectroscopy: In spectroscopy, the separation of different wavelengths and polarization states of light.
