The 100mm (4") diameter magnifier is ideal for general reading, viewing ancient coins, and scanning large fields of view. It comes with a felt-padded lens case. The Zeiss Multilayer Anti-Reflective Coating is highly recommended to eliminate the distracting glare of sun or room lighting which can bounce off of uncoated glass surfaces and make viewing difficult. Coated lenses are a must for long periods of detail viewing, especially when you must work outdoors or under fluorescent ceiling fixtures or other uncontrollable lighting. Zeiss#: Z00045-AR. Size: 1.5x. Color: black. Sold Individually. Case Qty: 1 .
