Ge-px-50.8-76 50.8 mm Dia. Germanium Plano-Convex Lens; EFL=75mm Uncoated

This is a Ge-px-50.8-76 50.8 mm Dia. Germanium Plano-Convex Lens, a high-quality optical component sourced from Alkor Technologies. The lens is designed with a spherical geometry, featuring a plano-convex shape and a circular base. The lens has a diameter of 50.8 mm and a thickness at the edge of 2.6 mm, which increases to 4 mm at the center.

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

The lens has an effective focal length (EFL) of 75 mm, which is the distance from the center of the lens to the focal point when the lens is focused at infinity. The lens does not have any coating, which means it is uncoated. This can result in a higher level of scattering and lower transmission compared to coated lenses, but it can also make the lens more cost-effective.

The lens's inner and outer radii are 0, indicating a plano-convex shape. The radius of curvature (R1) is 229.1 mm. This information can be useful when calculating the lens's optical power or when designing optical systems that include this lens.
