GEW16AR.20 74.9 mm Dia. Germanium Optical Parallel Flat Window; t=5mm 3-12µm

This optical window, sourced from MKS/Newport, is a high-quality flat window designed for use in optical systems. It features a base shape of a circle with a diameter of 74.9 mm and a thickness of 5 mm, providing a robust and stable platform for optical components.

The window is made from Germanium Burnett, a material known for its excellent optical properties, particularly in the infrared region of the spectrum. This specific window is designed for use with a wavelength of 10600 nm, making it ideal for applications in this spectral range.

The window's surfaces are coated with a new AR-20 coating on both the front and back, which provides excellent antireflective properties. This coating helps to minimize losses due to reflection, ensuring that the maximum amount of light is transmitted through the window.

The window's shape is that of a thin lens, which can provide some focusing or collimating properties, depending on the application. This makes it a versatile component in optical systems.
