The 62-561 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 12.7mm diameter and a 12.7mm focal length, making it a versatile choice for various optical applications. The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties.
The lens features a standard curve coating on both the front and back surfaces, specifically the EDM VIS-0 std curve. This coating is designed to enhance the lens's performance in the visible light spectrum, particularly between 425 and 675nm. The coating reduces surface reflections, improving light transmission and enhancing the overall efficiency of the optical system.
The lens's geometry is another notable feature. It has a thickness of 1.72mm at the edge and 4mm at the center. The inner and outer radii are 0, and the radius of curvature (R1) is 9.97mm. The back focal length (BFL) is 10.46mm, and the effective focal length (EFL) is 12.7mm. These parameters make the lens suitable for use in a wide range of optical systems.
