Editorial Review The Triplet Hawk Diamond Loupe is a 21mm 10x triplet with an European made lens that is corrected for chromatic (aplanatic) and spherical (achromatic) aberration. The lens has a special anti-reflection coating to minimize reflections from ambient light. The black color of the body also helps minimize reflections. It has an exclusive locking mechanism that keeps the lens protected at all times. The loupe comes in a protective box with a loupe chain with detachable clips. Also included is a certification and warranty document.
