This is a 5mm diameter, double-convex lens with a focal length of 25mm, sourced from Edmund Optics. The lens is made from the high-quality material n-BK7 Schott, which is known for its excellent optical properties. The lens features a front and back coating of edm vis ext, which enhances its transmission capabilities within the visible light spectrum, specifically between 350-700nm.
The lens has a center thickness of 1.5mm and an edge thickness of 1.26mm, providing a robust structure while maintaining a compact design. The inner and outer radii are not specified, indicating that they are not a significant factor in the lens's performance or description. The back focal length (BFL) is 24.5mm, which is a critical measurement for designing optical systems that include this lens.
This lens is a spherical lens, meaning it has a curved surface on both sides. The radii of curvature for the first and second surfaces are 25.58mm and -25.58mm, respectively. This specific curvature profile contributes to the lens's focusing power and overall optical performance.
