Hastings Triplet Magnifiers are truly the finest magnifiers Bausch & Lomb has to offer. Hastings Triplet Magnifiers incorporate three separate lenses, bonded together to form a compound lens to provide sharp, very distinct magnified image without distortion, even under 14x and 20x power magnification. A swing-away, nickel-plated case protects the lens and serves as a handle. For more information as well as questions to answers you may have, check out our Coin Magnifier Info Guide.
