This is a Ge-px-50.8-300 50.8 mm Dia. Germanium Plano-Convex Lens, sourced from Alkor Technologies. The lens is uncoated and features a spherical shape, designed for use in optical systems that require a focal length of 300mm.
The lens has a base shape of a circle, with a diameter of 50.8mm. The edge thickness of the lens is 2.5mm, while the center thickness is slightly greater at 2.9mm. The lens is made from Germanium burnett, a material known for its excellent optical properties, particularly in the infrared region of the spectrum. The lens is designed to operate at a wavelength of 10600nm.
The lens's geometry is such that it has an inner radius of 0mm and an outer radius of 0mm, with a planoconvex design. This design is often used in optical systems where a high level of optical power is required in a small package. The lens's EFL (Effective Focal Length) is 300mm, making it suitable for use in a variety of applications.
