This is a Si-px-25.4-63 25.4 mm Dia. Silicon Plano-Convex Lens, a high-quality optical component sourced from Alkor Technologies. The lens is uncoated and features a spherical shape, making it suitable for a wide range of optical applications.
The lens has a diameter of 25.4 mm and a thickness that varies from 2 mm at the edge to 2.5 mm at the center. The effective focal length (EFL) of this lens is 63.5 mm, which is a crucial parameter in determining the lens's focusing power. The lens's inner and outer radii are 0, indicating a plano-convex design, where one side of the lens is flat, and the other side is curved.
The lens is made of silicon, specifically silicon sal vil 1957, and is designed to work with a wavelength of 10600 nm. This makes it suitable for use in infrared (IR) applications. The lens's geometry, material, and coating are all carefully selected to ensure optimal performance in its intended application.
