Request InfoEdmund Optics Inc.New high-contrast IR wire-grid polarizers from Edmund Optics are suitable for broadband IR applications requiring high transmission and contrast, including spectroscopy, thermal imaging and astronomy. The polarizers are constructed by applying a thin layer of aluminum microwires to a glass window. Their design features a lightweight, thin silicon substrate, making them suitable for weight-sensitive systems such as unmanned aerial vehicles. The devices’ wire-grid technology allows the angle of incidence to vary more than 20° without exhibiting performance loss.
