WG70530-E2 0.5in Dia. AR Coated; ZnSe Broadband Precision Window; t=3 mm 4.5-7.5µm

The WG70530-E2 is a high-quality optical window from Thorlabs, designed for use in a broad range of applications. This window features a diameter of 0.5 inches (12.7 mm) and a thickness of 3 mm, providing a robust and stable platform for optical systems.

The window is made from ZnSe (Zinc Selenide), a material known for its excellent optical properties, including high transparency in the infrared region. This makes it ideal for applications that require the transmission of light in this spectrum, such as infrared spectroscopy or thermal imaging.

The WG70530-E2 is coated with Thorlabs' E2 AR coating, which is designed to reduce reflection and increase transmission across the 450-750 nm range. This coating ensures optimal performance in visible light applications, enhancing the overall efficiency of your optical system.

The window's geometry is defined by its thin lens shape, which provides excellent optical performance. The window's flat surface ensures minimal distortion, making it suitable for use in imaging systems or any application where optical quality is paramount.
