This item is a 10mm diameter x 25mm focal length double-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens is designed with a base shape of a circle and features a spherical geometry, making it suitable for a wide range of optical applications.
The lens has a diameter of 10mm, with a thickness of 1.51mm at the edge and 2.5mm at the center. The effective focal length (EFL) of the lens is 25mm, and it has a back focal length (BFL) of 24.16mm. The first radius of curvature (R1) is 25.41mm, while the second radius of curvature (R2) is -25.41mm. The inner and outer radii are both 0mm.
The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. It is designed to work with a wavelength of 587.6nm. The lens features a VIS 0° coating on both the front and back, providing standard curve performance. This coating enhances the lens's performance in the visible spectrum, making it ideal for applications that require high light transmission and clarity.
