Features
Brewster’s Angle Mounting and Tuning
Thin film polarizers are designed to transmit p-polarized light and reflect s-polarized light. This transmission and reflection is greatest at the angle of incidence – in this case, Brewster's Angle, with extinction ratios exceeding 100:1. When setting up your experiment, fine adjustments of the polarizer's position (angular tuning) around the angle of incidence may be required to realize optimal polarization performance.
Mounting Options
These rectangular polarizers can be mounted to a verity of our mounts such as
High Damage Threshold
These optics have been developed for use in some of the most demanding lasers in the industry. An advanced coating design is carefully placed on Grade A N-BK7 or UV Grade Fused Silica substrates through meticulous production procedures, resulting in damage thresholds of 5 MW/cm2 CW and 5 J/cm2 pulsed.
Advanced Coatings
Our HP.2, HP.4 and HP.6 coatings provide 100:1 extinction ratio, high efficiency (Tp>95%) and high laser damage resistance at their design wavelengths of 355, 532 and 1064 nm, respectively.
