63-720 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm
The 63-720 is a high-quality achromatic doublet lens, boasting a 10 mm diameter and an effective focal length of 30 mm, specifically designed for the visual (VIS) and near-infrared (NIR) spectrum, spanning 400-1000 nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their official website, currently listed as in stock.
The lens is constructed from two types of glass, 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-NIR 0SP2002000 coating, providing superior protection and performance across the VIS-NIR spectrum.
The lens geometry is meticulously designed, with a thickness of 4.48 mm at the edge, a center thickness of 3.5 mm, and a center thickness 'a' of 2 mm. The lens features three radii of curvature: r1 at 18.58 mm, r2 at -13.17 mm, and r3 at -37.11 mm. The inner and outer radii are 0 mm, indicating a circular shape.
This lens is a multiplet, meaning it is composed of multiple elements, which is reflected in its 'Sub Type'. The base shape is circular, and the lens is available in the Edmund Optics catalog under the catalog number 63-720.
