This is a Plano-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. The lens has a diameter of 75.0mm and a focal length of 75.0mm, making it a versatile choice for various optical applications. The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability.
The lens features a VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating on both the front and back surfaces. This coating enhances the lens's performance in the visible and near-infrared spectrum, between 400-1000nm. It reduces surface reflections, increases transmission, and improves overall system efficiency.
The lens's geometry includes a thickness of 3.66mm at the edge and 32.62mm at the center. The radius of curvature (R1) is 38.76mm, and the back focal length (BFL) is 53.49mm. The lens's shape is spherical, and it has no inner or outer radius, indicating a uniform curvature across the lens surface.
