This is the GE-ww-12.7-2, a 12.7 mm diameter Germanium Wedge Window, with a thickness of 2mm and no coating. The window is sourced from Alkor Technologies, a reputable vendor in the optical industry.
The GE-ww-12.7-2 is a Wedge Window, a type of optical window that is wedge-shaped to prevent interference patterns from forming between reflections. This particular model has a wedge angle of 0.008726646259971648 radians, providing a subtle but effective barrier against such interference.
The window is made of Germanium, specifically a material type referred to as "germanium burnett". Germanium is a common material in optical windows due to its high refractive index and transparency in the infrared region of the spectrum. The window's 12.7 mm diameter makes it suitable for a wide range of applications, from scientific research to industrial use.
The window's thickness of 2mm is uniform across the center, providing structural rigidity and resistance to deformation. The uncoated nature of the window means it does not have any additional layers to enhance its optical properties. However, this also means it can be easily integrated into existing optical systems without worrying about compatibility issues.
