47-653-INK 9 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=18mm VIS 0° 425-675nm
The 47-653-INK is a high-quality achromatic doublet lens, boasting a 9 mm diameter and an effective focal length (EFL) of 18 mm, specifically designed for the visible light spectrum ranging from 425 to 675 nm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase on their official website.
The lens is constructed from two distinct materials, N-BAF10 and N-SF10, 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 intricately designed, with a thickness of 4.49 mm at the edge, a center thickness of 4.32 mm, and a center thickness 'a' of 1.15 mm. The lens curvature is also precisely engineered, with radii r1 and r2 measuring 12.37 mm and -7.38 mm, respectively, and r3 at -73.86 mm. The lens is circular in shape and classified as a multiplet due to its complex construction.
