47-739 40 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=120mm VIS 0° 425-675nm
The 47-739 is a high-quality Achromatic Doublet Lens, boasting a 40 mm diameter and an effective focal length (EFL) of 120mm, 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 Schott glass, N-SSK8 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, enhancing its light transmission capabilities and overall performance.
The lens geometry is meticulously designed, with a thickness of 10.5mm at the edge, a center thickness of 9.6mm, and a center thickness 'a' of 4.2mm. The lens features three radii of curvature: r1 at 65.22mm, r2 at -62.03mm, and r3 at -1240.67mm. 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, which allows for superior optical performance. The 47-739 is currently in stock, ready for immediate purchase and use in your optical system.
