This is a Si-px-25.4-50 25.4 mm Dia. Silicon 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 25.4 mm and a thickness at the edge of 2 mm. The thickness at the center is slightly more, measuring 2.6 mm. The effective focal length (EFL) of this lens is 50.8 mm, providing a focused image at a reasonable distance. The lens is made of silicon, specifically silicon sal vil 1957, which is known for its excellent optical properties.
The lens is designed to work with a wavelength of 10600 nm. It does not have any coating, which means it is uncoated. This can be beneficial in certain applications where a coating might interfere with the desired optical properties.
