48-350 12.5 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-15mm MgF2 400-700nm

The 48-350 is a high-quality negative achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.5 mm, is designed for use in the visible spectrum, specifically between 400-700nm. The lens features a focal length of -15mm, making it suitable for a wide range of optical applications.

The lens is composed of two elements, N-BAF10 and N-SF10, both from Schott. These materials are known for their excellent optical properties, contributing to the lens' high performance. The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces, which enhances its transmission capabilities and protects it from environmental factors.

The geometry of the lens is carefully designed to optimize its performance. The edge thickness is 8.04mm, while the center thickness is 2mm. The lens also features a curvature radius of -10.62mm on the first surface and 8.63mm on the second surface. The inner and outer radii are 0mm, and the lens has a total length of 8.04mm.

This lens is a multiplet, meaning it is composed of multiple elements. The design and composition of this lens make it an ideal choice for various applications that require a high-performance, negative achromatic doublet lens.
