This is a Germanium Plano-Convex lens, sourced from Alkor Technologies, with a diameter of 25.4 mm and a focal length of 254 mm. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens's geometry is characterized by its diameter, thickness at the edge, and thickness at the center. The diameter is a constant 25.4 mm, while the thickness at the edge is 2 mm and at the center is 2.1 mm. The lens's inner and outer radii are both 0, indicating a plano-convex shape.
The lens is made of Germanium burnett, a specific type of germanium, and is designed to work with a wavelength of 10600 nm. The shape of the lens is spherical, which means it has a curvature that is the same along every meridian.
The lens's coating is listed as empty, which means it does not have any special coatings. This could affect the lens's performance in certain applications, so it's important to consider this factor when deciding if this lens is right for your needs.
