20X 21mm Rubber-coated Triplet Magnifier Jewelry Gem Loupe for Gem Identifying
The triplet-type loupe:
Three antireflection lenses joined to create perfect chromatic colour correction allowing you to see precisely and clearly.
Importance of Triplet-type:
Correction for visual distortion is the triplet-type creates what we call flatness of field.If we were to look at a gem with a magnifier
that was not a triplet-type,any flaw seen at an outer edge of the magnifying lens would be distorted,more or less so depending on how close the flaw is to the edge of viewing lens.
