47-672-INK 12.5 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=100mm VIS 0° 425-675nm

The 47-672-INK is a high-quality 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 light spectrum, specifically between 425 and 675 nanometers. The lens boasts an effective focal length (EFL) of 100mm, making it suitable for a wide range of optical applications.

The lens is composed of two elements, made from N-BK7 and N-SF5 Schott glass, respectively. These materials are chosen for their excellent optical properties, contributing to the lens's high-performance capabilities. The lens features a curvature defined by radii of 61.54mm and -44.39mm for the first element, and -130.26mm for the second element. The center thickness of the lens is 3mm, with a 1.5mm thickness at the edge.

The lens is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and improving transmission in the visible light spectrum. The lens is designed in a circular shape, with a multiplet geometry, further optimizing its optical performance.
