This is a Si-px-50.8-76 50.8 mm Dia. Silicon Plano-Convex Lens, a high-quality optical component sourced from Alkor Technologies. The lens is uncoated and features a plano-convex design, making it suitable for a wide range of optical applications.
The lens has a diameter of 50.8 mm and a thickness that varies from 2.5 mm at the edge to 4.3 mm at the center. The effective focal length (EFL) of this lens is 76.2 mm, which is a crucial parameter in determining the lens's focusing power. The lens's inner and outer radii are 0, indicating a planar surface on one side and a curved surface on the other.
The lens is made of silicon, specifically silicon sal vil 1957, and is designed to work with a wavelength of 10600 nm. The spherical shape of the lens ensures minimal distortion and high-quality image reproduction.
