47-349 25.0mm Dia. x 85.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
This is a 25.0mm diameter, 85.0mm focal length Plano-Convex lens, specifically designed for the visible light spectrum (425-675nm). The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.
The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, which enhances its light transmission capabilities and reduces surface reflections.
The lens geometry includes a 2.48mm edge thickness and a 4.3mm center thickness. The inner and outer radii are not specified, suggesting a uniform curvature. The lens's effective focal length (EFL) is 85mm, and the back focal length (BFL) is 82.17mm. The radius of curvature (R1) is 43.93mm.
This lens is a Spherical type, indicating that its surfaces are sections of a sphere. The base shape is Circular, implying that the lens has a circular cross-section.
