High contrast 45 deg thin film polarizer

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° thin film polarizers are specially designed for optimal performance at a 45° 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:
