High-contrast IR wire grid polarizers from Edmund Optics are suited for broadband IR applications that require high transmission and contrast, including spectroscopy and thermal imaging. The polarizers are made by applying a thin layer of aluminum microwires to a glass window. They are designed using a lightweight, thin silicon substrate, making them well suited for weight-sensitive systems such as unmanned aerial vehicles. The devices feature wire grid technology, which allows the angle of incidence to vary ±20° without exhibiting performance loss. They are anti-reflective coated for superior transmission, and provide high heat resistance with low thermal expansion.

Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
