WGE2911 11.7 x 29.5 mm Germanium Rectangular Window; t=1mm Uncoated

This is a WGE2911 Germanium Rectangular Window, a high-quality optical component sourced from Knight Optical. The window measures 11.7 mm in width and 29.5 mm in length, making it suitable for applications that require a larger aperture. With a thickness of 1 mm, it provides excellent mechanical strength while maintaining minimal optical distortion.

The window is made of Germanium, a material known for its high refractive index and transparency in the infrared region, specifically at 10600 nm. This makes it ideal for applications in the infrared spectrum, such as thermal imaging, spectroscopy, and other infrared-based technologies.

The window is uncoated, which means it does not have any anti-reflective or other surface coatings. This can be beneficial in certain applications where the natural properties of Germanium are desired, or where coatings may interfere with the optical system. However, it's important to note that uncoated windows can have higher reflectivity, which may need to be considered in the overall system design.

The window is of the flat window type, which means it does not have any curvature. This is beneficial in applications where flatness is critical, such as in beam splitters, windows, and other components where planarity is a key requirement.
