Linear Polarizers

Our linear polarizers come in standard sizes for use with our rotary optical mounts.  They are used to to linearly polarize incoming light.

Achromatic Wave Plates

Our achromatic waveplates use two birefringent crystalline materials to provide a constant phase shift independent of wavelength.

Variable Wave Plates

Berek’s variable waveplates modify the polarization of collimated beams from any state to any other state with the flexibility, convenience, and precision previously found only in bulky and expensive Soleil-Babinet compensators. True zero-order retardance, minimal wavefront distortion, and beam displacement of less than 150 µm are all featured at an economical price.
