580-6123 25.4 mm Dia. AR coated Germanium Flat Window; t=3.0 mm 10.6µm

This is a high-quality optical window offered by EKSMA Optics, a renowned vendor in the field of UV and IR optics. The window, identified as item number 580-6123, is designed with a base shape of a circle and a diameter of 25.4 mm, making it suitable for a wide range of optical applications.

The window's thickness is 3.0 mm, providing a good balance between durability and light transmission. It is made of Germanium (Ge), a material known for its excellent transmission properties in the infrared region of the spectrum, specifically at 10.6 µm. This makes the window ideal for applications that require efficient transmission of infrared light.

The window features Anti-Reflective (AR) coatings on both the front and back surfaces. The coating, identified as 'eks ge ar 10600', is specifically designed to reduce reflection at the wavelength of 10.6 µm. This coating enhances the window's performance by allowing more light to pass through, thereby reducing losses due to reflection.

The window is shaped as a thin lens, suggesting that it may have some focusing properties. However, the specific lens parameters are not provided in the data. Therefore, it is recommended to consult the vendor for detailed lens parameters if required.
