Polarization optics are important for both intra and extra-cavity use. Some advanced applications require precision-beam combinations for which the polarization state is extremely important. Dualband Brewster Thin Film polarizers are designed for use with two collinear beams of different wavelengths, while maintaining the performance of a regular Brewster polarizer.

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.

Contact us so we can help you with your challenge. We have an experienced team of coating engineers and metrology capabilities to prototype and transfer your idea into a well-defined production process.
