48-351 25 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-30mm MgF2 400-700nm
The 48-351 is a high-quality negative achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 25 mm, is designed for use in the visible spectrum, specifically between 400-700nm. The lens features a focal length of -30mm, 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's extensive material library. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens's geometry is carefully designed, with an inner radius of 0 and an outer radius of 0, ensuring optimal light transmission.
The 48-351 lens features a center thickness of 4mm and an edge thickness of 16.31mm, providing robustness and stability. The lens also has an aspheric surface (r3: 162.24) that helps to minimize spherical aberration, enhancing the image quality.
The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces, ensuring high transmission and durability. This coating is designed to provide a standard curve, ensuring consistent performance across different applications.
