45-292 9mm Dia. x 45mm FL Uncoated; Double-Convex Lens
The 45-292 is a 9mm diameter, double-convex lens with a focal length of 45mm, sourced from the reputable optical vendor, Edmund Optics. This lens is uncoated, which means it does not have any additional layers to enhance light transmission or protect the surface. The lens's base shape is circular, and it falls under the category of Spherical Lens (Convex-Convex) in the Sub Type field.
The geometry of the lens is meticulously designed. The edge thickness is 2.06mm, while the center thickness is 2.5mm. The effective focal length (EFL) is 45mm, and the radii of curvature are 46.08mm for the first surface and -46.08mm for the second surface. The back focal length (BFL) is 44.17mm. The lens does not have any inner or outer radius specified, indicating a uniform curvature.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. The wavelength for this lens is 587.6nm, which is in the visible light spectrum.
Please note that this lens is uncoated, which may affect its performance in certain applications. It is crucial to consider the specific requirements of your project before deciding on this lens.
