SLB-50.8B-170P 50.8 mm Dia. x 171.1 mm FL; Double-Convex Lens Uncoated
OptoSigma presents the SLB-50.8B-170P, a 50.8 mm diameter x 171.1 mm focal length double-convex lens made of n-bk7 schott material. This uncoated lens is designed for general-purpose use and is currently in stock, as indicated by its weblink status.
The SLB-50.8B-170P is a spherical lens with a base shape of a circle. Its geometry includes a 2.4 mm thickness at the edge, a 6.1 mm thickness at the center, and an effective focal length (EFL) of 171.1 mm. The first radius of curvature (R1) is 176.46 mm, while the second radius of curvature (R2) is -176.46 mm, which indicates its double-convex shape. The back focal length (BFL) is 169 mm, and both the inner and outer radii are 0 mm.
This lens is available in a single wavelength of 546.1 nm. The coating is not specified, which means it is likely uncoated. The provided item data does not include any additional information about coatings or specialized applications.
