This is a Ge-px-25.4-500 25.4 mm Dia. Germanium Plano-Convex Lens, sourced from Alkor Technologies. The lens is designed with a spherical shape and a base shape of a circle. It has a diameter of 25.4 mm and a thickness at the edge and center of 2 mm each. The effective focal length (EFL) of this lens is 500mm, making it suitable for applications that require long-range focus.
The lens is made of Germanium burnett, a material known for its excellent optical properties, particularly in the infrared spectrum. The wavelength of this lens is 10600 nm, which is within the infrared region. This makes the lens ideal for applications such as thermal imaging, night vision, and other infrared-based technologies.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not necessarily diminish its performance, especially if the lens is used in the right conditions and applications.
