This is a Germanium Plano-Convex lens, sourced from Alkor Technologies, with a diameter of 25.4 mm and a focal length of 12.7 mm. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes an edge thickness of 1.3 mm and a center thickness of 2.5 mm. The inner and outer radii are both 0, indicating a uniform curvature.
The lens is made of Germanium burnett, a specific type of germanium that is often used in optical applications due to its high refractive index and transparency in the infrared region. The lens is designed to work with a wavelength of 10600 nm.
