The 45-134 is a high-quality double-convex lens, boasting a 6mm diameter and a 30mm focal length. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock. The lens is made from the renowned material, n-BK7 Schott, which is known for its excellent optical properties.
The lens features a standard MgF2 coating on both the front and back surfaces, which is applied using Edmund Optics' proprietary coating process. This coating enhances the lens' performance in the 400-700nm wavelength range, providing improved transmission and reduced reflection.
The geometry of the lens is meticulously designed, with an edge thickness of 2mm and a center thickness of 2.3mm. The lens' effective focal length (EFL) is 30mm, and it has a back focal length (BFL) of 29.23mm. The first and second radii of the lens are 30.61mm and -30.61mm, respectively. The lens' inner and outer radii are both 0mm, indicating a uniform curvature.
