Ge-px-38.1-200 38.1 mm Dia. Germanium Plano-Convex Lens; EFL=200mm Uncoated

This is a Ge-px-38.1-200 38.1 mm Dia. Germanium Plano-Convex Lens, a high-quality optical component sourced from Alkor Technologies. The lens is designed with a spherical shape and a base shape of a circle, making it suitable for a wide range of optical applications.

The lens has a diameter of 38.1 mm and a thickness at the edge of 2 mm. The thickness at the center is slightly more, measuring 2.3 mm. The effective focal length (EFL) of this lens is 200 mm, making it a medium to long-focus lens. The inner and outer radii of the lens are 0, indicating a plano-convex design, where one side of the lens is flat (plano) and the other side is curved (convex).

The lens is made of Germanium burnett, a material known for its excellent optical properties, particularly in the infrared region of the spectrum. The lens is designed to work with a wavelength of 10600 nm, making it suitable for applications in the infrared spectrum.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
