Hastings Triplet Magnifiers
Highly corrected magnifiers that are Bausch & Lombs finest. Three separate optical glass lenses, bonded together to form a compound lens, provide sharp, very distinct magnified images - even under 10 power magnification. Lens sides are coated black to block out all glare. A swing away nickel plated case protects the lens and serves as a handle. The focal distance is 25.4mm.
