48-349 9 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-18mm MgF2 400-700nm
The 48-349 is a high-quality negative achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.
The lens features a 9mm diameter and a focal length of -18mm, providing a compact and efficient optical solution. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The negative doublet design helps to correct chromatic aberration, ensuring sharp and clear images.
The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, reducing reflections and improving overall light efficiency.
The lens geometry is carefully designed to provide optimal performance. The edge thickness is 5.12mm, while the center thickness is 1.44mm. The lens also features a series of radii (r1=-35.51mm, r2=6.11mm, r3=16.2mm) that contribute to its excellent optical performance.
