This is a Germanium Wedge Window, sourced from Alkor Technologies, a renowned vendor in the optical industry. The window has a base shape of a circle with a diameter of 25.4 mm, making it suitable for a wide range of applications. The window's thickness at the center is 4 mm, providing substantial structural integrity.
The window features a wedge shape, which is characterized by a wedge angle of 0.008726646259971648 radians. This wedge shape can help minimize optical aberrations in certain applications. The window is made of Germanium burnett, a material known for its excellent optical properties, particularly in the infrared region of the spectrum.
The window is designed for use at a wavelength of 633 nm. It is uncoated, which means it does not have any additional layers of material applied to its surface to alter its optical properties. This can make it suitable for applications where the natural properties of Germanium are desired.
