WGE5012 50 mm Dia. Germanium Round Window; t=1mm AR 3-12µm

This is the WGE5012, a 50 mm diameter Germanium Round Window with a thickness of 1 mm, designed and manufactured by Knight Optical. The window features Anti-Reflective (AR) coatings on both the front and back surfaces, specifically tailored for the 3-12 µm wavelength range.

The WGE5012 is a Flat Window, which means it has a planar surface on both sides, ideal for applications that require minimal optical distortion. Its circular base shape, with a diameter of 50 mm, is universally applicable across various optical systems. The window's thin lens shape further enhances its versatility, making it suitable for a wide range of applications.

The window is made of Germanium burnett, a material known for its excellent transmission properties in the infrared region of the spectrum. This makes the WGE5012 an ideal choice for applications that operate within the 3-12 µm wavelength range, such as thermal imaging, infrared spectroscopy, and other infrared-based technologies.

The window's AR coatings are designed to reduce surface reflections, thereby enhancing the transmission of light through the window. This is particularly beneficial in applications where high light transmission is critical. The AR coatings are applied to both the front and back surfaces of the window, ensuring optimal performance from both sides.
