Optical systems requiring precise polarization control need polarizers that combine high extinction performance, a wide acceptance angle, and consistent optical quality.

Cening Optics Glan-Thompson polarizers consist of two matched calcite prisms cemented together. The extraordinary ray is transmitted, while the ordinary ray is deflected and absorbed, providing effective linear polarization.

With an extinction ratio of 5×10?:1 and a 14–16° field angle, these polarizers are well suited to optical designs requiring both high polarization purity and a large field of view. A surface quality of 20-10 S/D, clear aperture greater than 90%, and single-layer MgF? coating on both sides further support reliable optical performance.

Cening Optics supports customized manufacturing for different optical system requirements, combining precision calcite prism processing, optical surface control, prism cementing and assembly, and optical coating capabilities.
