Otto Frei Gold 10X Triplet Loupe with 18 mm Diameter Lens, Rubber Grip & Case

The 10X Triplet Loupe with 18 mm Diameter Lens is a professional-grade magnifier built for diamond grading, gemstone evaluation, and fine detail inspection at the bench. Triplet loupes are the industry standard for serious jewelers — three lenses bonded together deliver superior optical performance compared to singlet or doublet designs.

This loupe is corrected for both spherical aberration (minimizing edge distortion) and chromatic aberration (eliminating color fringing at the edges), ensuring a sharp, accurate, true-color view across the full field of view. For clarity grading purposes, if a flaw is not visible under 10X magnification, it does not exist — making an optically precise 10X triplet an essential tool for any professional gemologist or bench jeweler.

The 18 mm lens diameter provides a wide field of view, and the non-slip rubber grip makes extended use comfortable and secure. Each loupe includes a faux leather pouch for protection and portability.
