Hastings Triplets, the finest hand lenses made by Bausch & Lomb, are highly corrected for spherical and chromatic aberration. Their compound lens is formed from three separate lenses bonded together and provides very distinct images with no color distortion. A swing-away, nickel-plated case protects the lens and serves as a handle.
