This is a 69-372 Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts a 9.0mm diameter and a 12.0mm focal length, making it suitable for a wide range of optical applications.
The lens is fabricated from n-sf11 Schott, a high-index glass that offers excellent optical performance. It features a plano-convex geometry, where one side is flat (plano) and the other side is curved (convex). This geometry is characterized by a 9.42mm radius of curvature on the curved side.
The lens has a central thickness of 2.5mm and an edge thickness of 1.36mm, providing robustness and durability. The effective focal length (EFL) of the lens is 12mm, which is the distance from the lens's center to the focal point.
The lens is coated with Edmund Optics' Las V-Coat 532, a high-quality coating designed for laser applications at a wavelength of 532nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it ideal for laser systems.
