This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 38-312, is designed with a diameter of 15.0mm and a focal length of 50.0mm, making it suitable for a wide range of optical applications.
The lens is made from the high-quality material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including high transmission in the visible spectrum. The lens's geometry includes a thickness of 1.39mm at the edge and 2.5mm at the center, with an effective focal length (EFL) of 50mm. The radius of curvature (R1) is 25.84mm, and the back focal length (BFL) is 48.35mm.
The lens features a VIS 0° coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the visible spectrum (425-675nm). The coating is standard, ensuring consistent performance and reliability.
