47-713 30 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=50mm VIS 0° 425-675nm
The 47-713 is a high-quality achromatic doublet lens, boasting a 30 mm diameter and an effective focal length (EFL) of 50 mm, specifically designed for the visible light spectrum ranging from 425 to 675 nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their official website.
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 the EDM VIS-0 standard curve coating, providing improved light transmission and protection against environmental factors.
The lens geometry is meticulously designed, with a thickness of 9.25 mm at the edge, a center thickness of 11 mm, and a central thickness 'a' of 2.2 mm. The lens features three radii of curvature: r1 at 34.81 mm, r2 at -22.12 mm, and r3 at -203.48 mm. The inner and outer radii are both zero, indicating a circular shape.
This lens is classified as a multiplet, a type of lens composed of multiple elements. Multiplets are often used in optical systems to correct aberrations and improve image quality. The 47-713 is no exception, offering superior image quality and optical performance.
