11-862 25.4 mm Dia. Germanium Protective Flat Window; t=3 mm Uncoated

The 11-862 is a circular, flat window made from high-quality germanium, sourced from the reputable vendor Edmund Optics. With a diameter of 25.4 mm and a thickness of 3 mm, this window is designed to provide robust protection for optical systems while minimally affecting the path of light.

This window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where a specific coating may interfere with the desired optical properties. However, it's important to note that uncoated windows may have higher reflectivity compared to coated ones, especially at certain wavelengths.

The window is designed to operate at a specific wavelength of 587.6 nm, making it suitable for applications that require precise optical performance at this wavelength. This could include various fields such as spectroscopy, laser technology, or optical metrology.
