LA9942-E3 25.4 mm Dia. Germanium Plano-Convex Lens; EFL=1000mm 7-12µm
This is a LA9942-E3 25.4 mm diameter Germanium Plano-Convex lens, designed for use in the infrared spectrum with a wavelength of 10600 nm. The lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.
The lens is spherical in shape, with a base shape of a circle. It has a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The diameter of the lens is 25.4 mm, and it has a thickness of 2 mm at the edge and the center.
The effective focal length (EFL) of this lens is 1000 mm, which is the distance from the center of the lens to the focal point where light rays converge. This makes it suitable for applications that require a long focal length.
The lens is made of Germanium, a material with a high refractive index and excellent transparency in the infrared region. It is coated with tho e3gearc700012000 on both the front and back surfaces, which is a specialized coating designed for use in the infrared spectrum.
