Newport 20RP32-632.8 Zero-Order Waveplate Polymer, 1/2 New

The Newport 20RP32-632.8 is a zero-order half-wave plate designed for precise polarization control at a wavelength of 632.8 nm. This wave plate consists of a birefringent polymer film sandwiched between two high-precision, broadband antireflection-coated N-BK7 windows, ensuring excellent transmitted wavefront quality and λ/2 retardation while minimizing beam deviation and surface reflection losses.

Key Features:

• Wavelength: Optimized for 632.8 nm, suitable for applications involving HeNe lasers.

• Retardation: Provides half-wave (λ/2) retardation, effectively rotating the polarization direction of linearly polarized light.

• Construction: Comprises a birefringent polymer film between two N-BK7 windows, offering durability and stability.

• Diameter: Available in a 50.8 mm diameter, facilitating integration into various optical setups.

• Mounting: Housed in a black anodized aluminum mount for protection and ease of handling.

Zero-order wave plates like the 20RP32-632.8 are preferred in applications requiring high precision and stability, as they exhibit lower sensitivity to temperature and wavelength variations compared to multiple-order wave plates. This makes them ideal for use in interferometry, laser optics, and other polarization-sensitive experiments.
