Waveplates and Retarders
Excelitas polarization control portfolio provides versatile solutions for precise phase manipulation across a broad spectrum of optical applications. λ/4 retardation films offer a lightweight, achromatic method for converting linear to circular polarization, optimized for 450–650 nm and suitable for integration into compact systems. High-precision crystal quartz retardation plates achieve exceptional accuracy with λ/500 retardation tolerance, low wavefront distortion, and high stability, and are available in both single- and zero-order configurations. Achromatic zero-order waveplates feature high transmission across wide wavelength ranges, robust cemented construction, and strong resistance to damage. Collectively, these technologies enable reliable polarization control, minimal wavefront error, and adaptable system integration for laboratory optics and demanding laser applications.
