47-671 12.5 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=90mm VIS 0° 425-675nm
The 47-671 is a high-quality achromatic doublet lens, boasting a 12.5 mm diameter and an effective focal length (EFL) of 90mm, specifically designed for the visible light spectrum ranging from 425 to 675nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website.
The lens is constructed from two types of materials, N-BK7 and N-SF5, both from Schott, ensuring excellent optical performance. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, providing superior light transmission and protection against environmental factors.
The lens geometry is meticulously designed, with a thickness of 3.06mm at the edge, 1.98mm at the center, and 1.6mm at the center a. The radii of the curvature are r1=55.8, r2=-40.17, and r3=-116.32, contributing to the lens's exceptional optical properties.
This achromatic doublet lens is a Multiplet type, offering superior image quality and color correction compared to single element lenses. It is ideal for various applications, including imaging systems, beam shaping, and optical instrumentation.
