47-637-INK 25 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=50mm VIS 0° 425-675nm
The 47-637-INK is a high-quality Achromatic Doublet Lens, sourced from the renowned optical vendor Edmund Optics. This lens boasts a 25 mm diameter and an effective focal length (EFL) of 50 mm, designed for use within the visible light spectrum, specifically between 425-675 nm.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The front and back surfaces of the lens are coated with EDMM Vis-0 Standard Curve coatings, enhancing its performance and durability.
The lens geometry is intricately designed, with a thickness of 8.79 mm at the edge, a center thickness of 9 mm, and an inner radius of 0 mm. The first and second radii of curvature are 34.53 mm and -21.98 mm, respectively, while the third radius of curvature is -214.63 mm. The lens also features a small central aperture with a thickness of 2.5 mm.
This lens is a multiplet, meaning it is composed of multiple optical elements. It is designed to correct chromatic aberrations, ensuring sharp, clear images across the entire visible light spectrum. The lens is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
