Brewster Angle Polarizer

Product Overview:

The Venuslab VLBP Series are thin-film plate polarizers optimized for use at the Brewster Angle (approx. 56°). Unlike standard absorptive polarizers, these optics utilize high-efficiency dielectric coatings to separate S-polarized and P-polarized light with minimal absorption, making them ideal for intra-cavity laser applications and high-power beam steering.

When oriented at the Brewster angle, the P-polarized component is transmitted with high efficiency (Tp > 98%), while the S-polarized component is reflected (Rs > 99%). This design eliminates the need for optical cement, significantly increasing the laser induced damage threshold (LIDT) compared to cemented polarizing cubes.

Application Note:

Mounting Tip: To achieve maximum extinction ratio, precise angular alignment is required. These polarizers are best mounted in kinematic rotation mounts to fine-tune the angle to the exact Brewster condition.
