Ge-px-38.1-150 38.1 mm Dia. Germanium Plano-Convex Lens; EFL=150mm Uncoated

This is a Ge-px-38.1-150 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 2.4 mm. The effective focal length (EFL) of this lens is 150 mm, providing a long focal length that can be beneficial in many 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, indicating its suitability for infrared applications.

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 situations. For instance, uncoated lenses can be more cost-effective and can sometimes provide better performance in specific conditions.
