The 5540 Berek's Variable Wave Plates modifies 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. The Model 5540 features true zero-order retardance, minimal wavefront distortion, and beam displacement of less than 150 µm-all at an economical price.
