Used for inspection of plant, rock or insect specimens. Also used to see details of coins, stamps or to assist with antique provenance.
Bausch & Lomb 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 strong 20 power magnification.
The sides of the lenses are coated black to reduce glare when using. The swing-away, nickel-plated case protects the lens and also serves as a handle. Protecting bag has drawstring closure.
