This is a Si-px-25.4-76 25.4 mm Dia. Silicon 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 convex lens.
The lens has a diameter of 25.4 mm and a thickness at the edge of 2 mm. The center thickness is slightly greater at 2.4 mm. The effective focal length (EFL) of this lens is 75 mm, making it suitable for applications that require a longer focal length.
The lens is made of silicon, specifically silicon sal vil 1957, and is designed to work with a wavelength of 10600 nm. The base shape of the lens is circular, and it does not have any inner or outer radius specified, indicating that it is a simple plano-convex lens.
