32-913 18 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=50mm MgF2 400-700nm
The 32-913 is a high-quality achromatic doublet lens, 18 mm in diameter, with an effective focal length (EFL) of 50mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website. The product page indicates that the item is currently in stock, ensuring prompt delivery upon order placement.
The lens is composed of two types of glass, N-SSK8 and N-SF10, both from Schott. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens features a front and back coating of MgF2, which is standard for Edmund Optics and provides a broad spectral range of 400-700nm. This coating enhances the lens's light transmission capabilities and reduces surface reflections.
The lens's geometry is meticulously designed, with a thickness of 5.69mm at the edge and 5mm at the center. The inner and outer radii are 0, suggesting a simple, circular shape. The first and second radii of curvature are 27.12mm and -25.66mm, respectively, while the third radius of curvature is -538.7mm. These parameters contribute to the lens's precise optical performance.
