The 11-864 is a circular, flat window made from high-quality germanium, sourced from the reputable vendor Edmund Optics. With a diameter of 76.2 mm and a thickness of 5 mm, this window is designed to provide robust protection for optical systems while minimizing distortion and loss of light.
This window is uncoated, which means it does not have any additional layers applied to its surface. While coatings can enhance the performance of optical elements in specific applications, an uncoated window offers the advantage of simplicity and versatility. It can be used in a wide range of applications without the need to consider the specific properties of a coating.
The window is designed to operate at a wavelength of 587.6 nm, which is in the visible light spectrum. This makes it suitable for use in applications where visibility and clarity are crucial. The window's thin lens shape further contributes to its performance, helping to maintain the integrity of the light path.
