This is a Plano-Convex lens, type of spherical lens, sourced from the renowned optical vendor, Edmund Optics. The lens has a circular base shape with a diameter of 12.0mm and a focal length of 100.0mm. The lens's geometry includes an edge thickness of 2.15mm and a center thickness of 2.5mm. The effective focal length (EFL) is 100.0mm, and the first radius of curvature (R1) is 51.68mm. The back focal length (BFL) is 98.35mm.
The lens is made of the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is widely used in various optical applications, such as beam expanders, laser systems, and imaging systems.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, with a spectral range of 500-1100nm, is designed to enhance the lens's performance by reducing surface reflections and increasing transmission. The YAG-BBAR coating is particularly suitable for applications involving high-power lasers and broadband light sources.
