This 9.0mm diameter by 25mm focal length plano-convex lens, sourced from the renowned optical component vendor Edmund Optics, is a high-quality spherical lens designed for use within the visible light spectrum. The lens boasts a plano-convex geometry, featuring a flat front surface and a curved back surface, with a base shape of a circle.
The lens's geometry details include a 1.19mm edge thickness, a 2mm center thickness, and a 25mm effective focal length (EFL). The front surface radius of curvature is 12.92mm, and the back focal length (BFL) is 23.68mm. The lens's inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface.
The lens is crafted from the well-regarded N-BK7 glass from Schott, a material known for its excellent optical properties and versatility. The lens's coating, VIS-EXT, is applied to both the front and back surfaces, enhancing its performance within the visible light spectrum (350-700nm). This coating helps minimize surface reflections and increase transmission, making it an ideal choice for various applications.
