Using lasers in industrial applications creates new challenges in making devices smaller and cheaper, while also robust and repeatable.

Polarization optics are important for both intra and extra-cavity use. By having high-contrast thin film polarizer in their design, laser engineers can save on weight and volume in their devices without influencing the output. High-contrast 45-degree thin film polarizers are specially designed for optimal performance at a 45-degree angle of incidence, which makes them easy to place and adjust in laser systems using standard optical mounts.

We design thin film polarizers in-house for both high LIDT and high polarization ratios. 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.
