Polymer waveplate #2893

zero ordertrue

Product Overview
Zero-order waveplates (retarders) consist of carefully aligned birefringent polymer sheets laminated between two precision N-BK7 windows. Available in standard quarter-wave (λ/4) and half-wave (λ/2) variants for common visible and near-infrared wavelengths. The true zero-order design ensures stable retardance with incidence angle and an improved angular field of view.

Key Features

• Available retarders: quarter-wave (λ/4) and half-wave (λ/2)
• True zero-order performance with excellent angular field of view
• Construction: birefringent polymer stack laminated between two precision N-BK7 windows
• Indexed in a metal ring; fast axis clearly marked
• High damage threshold: 500 W/cm2

Applications
Designed for optics and photonics systems that require precise control of polarization in the visible and near-infrared (NIR) spectral regions. Suitable for instruments and assemblies with moderate angular tolerance where minimal retardance variation with angle is required.
