This is a Ge-px-11.5-5.3 11.5 mm Dia. Germanium Plano-Convex Lens, a high-quality optical component sourced from Alkor Technologies. The lens, with a diameter of 11.5 mm, is designed for use in the infrared spectrum, specifically at a wavelength of 10600 nm.
The lens is spherical in shape, with a plano-convex geometry. This means that one side of the lens is flat (plano), while the other side is curved (convex). The curvature of the convex side is defined by a radius of 16 mm. The lens has an effective focal length (EFL) of 5.3 mm, which is the distance from the lens's center to the focal point.
The lens's thickness varies from 0.65 mm at the edge to 1.71 mm at the center. Notably, it does not have any inner or outer radius, indicating a uniform curvature across the convex side.
This lens is made of germanium burnett, a specific type of germanium known for its excellent optical properties in the infrared spectrum. The lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from environmental factors.
