47-481 6mm Dia. x 18mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-481 is a high-quality double-convex lens, sourced from the reputable optical vendor, Edmund Optics. This lens boasts a 6mm diameter and a focal length of 18mm, making it suitable for a wide range of optical applications.
The lens is crafted from Schott's n-BK7 glass, a popular material in the optical industry due to its excellent optical properties and versatility. The base shape of the lens is circular, contributing to its broad applicability in various optical systems.
The 47-481 lens features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 std curve. This coating is designed to optimize performance within the visible light spectrum, spanning from 425 to 675nm. This makes the lens ideal for applications that require high transmittance and minimal reflection within this spectral range.
The lens geometry is meticulously designed, with an edge thickness of 1.7mm and a center thickness of 2.2mm. The front and back radii of curvature are 18.22mm and -18.22mm, respectively, contributing to the lens's double-convex shape. The back focal length is 17.26mm, and both the inner and outer radii are 0mm, indicating a uniform curvature throughout the lens.
