THIN FILM POLARIZERS

Polarization optics is important for both intra and extra cavity use. By having high contrast thin film polarizer in their design, laser engineers can save weight and volume within their devices without influencing the output. Due to its high damage threshold and high extinction ratio, thin film polarizers are a good alternative to Glan laser polarizing prisms or cube polarizing beamsplitter.
