45-354 50 mm Dia. N-BAK4/N-SF10 Achromatic Doublet; EFL=350mm MgF2 400-700nm
The 45-354 is a high-quality achromatic doublet lens, boasting a 50 mm diameter and a focal length of 350 mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website. The product link provided is currently valid and indicates that the item is in stock.
The lens is constructed from two types of glass, N-BAK4 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 EDM MgF2 std curve, which enhances its light transmission capabilities and reduces surface reflections.
The lens's geometry is carefully designed, with a diameter of 50 mm, a thickness at the edge of 10.07 mm, and a center thickness of 8 mm. The inner and outer radii are 0 mm, and the lens has a central thickness 'a' of 4 mm. The curvature radii are R1 = 227.16 mm, R2 = -174.83 mm, and R3 = -571.49 mm. These specifications contribute to the lens's high-quality imaging capabilities.
