580-6155 50.8 mm Dia. AR coated Germanium Flat Window; t=5.0 mm 10.6µm

This is a high-quality optical window from EKSMA Optics, a renowned vendor in the field of UV and IR optics. The window, identified as 580-6155, is a flat window with a diameter of 50.8 mm and a thickness of 5.0 mm.

The window is made of Germanium, specifically the burnett variant, which is known for its excellent optical properties. It is designed to work with a wavelength of 10.6 µm, making it suitable for infrared applications.

The window features anti-reflective (AR) coatings on both the front and back surfaces. The coating, labeled 'eks ge ar 10600', is specifically designed to reduce reflection and increase transmission at the specified wavelength. This makes the window ideal for use in high-transmission optical systems.

The window is shaped as a thin lens, suggesting that it may have some light-bending properties. However, the specific optical power or curvature of the lens is not provided in the item data.
