Aluminium housings - Import export

Calomel IR polarizers are the only crystalline prismatic polarizers applicable in the mid-IR and LWIR spectral regions on the market. Beside the Calomel prismatic polarizers, only wire grid systems are currently available with no other birefringent crystal transparent above 6µm. The combination of Calomel´s two unique material properties: a high value of birefringence (Δn=0.683) and a wide transparency range (0.4μm-17μm), makes it a great material for mid-infrared polarizers and phase delay components. Our Calomel Wollaston polarizer is designed for the most demanding applications that require two separately accessible, high purity orthogonal linearly polarized beams. The air-spaced prism pair is assembled into a 30.0 mm diameter black anodized aluminium housing with a 10x10 mm clear aperture.
