Product Description
You can tell the difference by the amount of distortion at the edges or color fringing. To test a loupe, hold it a half-inch from newsprint and make sure everything is in focus from one edge to another. Then hold it over flat white paper. If it takes on a beige tone, it’s not a triplet
