This is a Plano-Convex lens, type L110-0223E, sourced from EKSMA Optics. The lens has a base shape of a circle and is made of BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and high chemical resistance. The lens has a diameter of 25.4 mm and a center thickness of 3.2 mm, with the edge thickness being 1.9 mm.
The lens is designed for a focal length of 125 mm, which is the distance from the lens's center to the point where the light rays converge. The lens's front surface has a radius of curvature of 64.8 mm, while the back surface is flat. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
This lens is suitable for applications that require a simple, high-quality lens with a long focal length. It can be used in various fields, including imaging, illumination, beam shaping, and beam manipulation. The lens's high-quality BK7 Schott glass ensures excellent image quality and low optical aberrations, making it an ideal choice for various optical systems.
