49-851 25.4mm Dia. x 76.2mm FL; Plano-Convex Lens Uncoated
The 49-851 is a Plano-Convex lens with a diameter of 25.4mm and a focal length of 76.2mm, 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 geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 1.9mm, while the center thickness is 4mm. The effective focal length (EFL) is 76.2mm, and the radius of curvature (R1) is 39.38mm. The back focal length (BFL) is 73.56mm, and both the inner and outer radii are 0mm.
The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The lens is designed to operate at a wavelength of 587.6nm. The shape of the lens is spherical, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance.
