Brewster type thin film polarizers
Having lasers in industrial applications creates new challenges of making the device smaller, and cheaper, but robust and repeatable as well.
Polarization optics are important for both intra and extra-cavity use. By having high contrast thin film polarizers 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 replacement for Glan laser polarizing prisms or cube polarizing beamsplitter.
We design thin film polarizers in-house for high LIDT and high polarization ratio at the same time. Each coating batch is tested to confirm all spectral characteristics. Typical Laser damage threshold reports can be found on our website: www.altechna.com/lidt.
