Ge-px-38.1-127 38.1 mm Dia. Germanium Plano-Convex Lens; EFL=127mm Uncoated

This is a Ge-px-38.1-127 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, transitioning to a center thickness of 2.5 mm. The effective focal length (EFL) of this lens is 127 mm, providing a long focal length for various optical systems. The lens is made of Germanium burnett, a material known for its excellent optical properties, particularly in the infrared region of the spectrum. The wavelength of this lens is 10600 nm, making it ideal for applications that require transmission in the infrared range.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications. The inner and outer radii of the lens are 0, indicating a plano-convex design, where one side of the lens is flat, and the other side is curved.
