Hastings Triplet Loupe
Bausch & Lomb engineers the Hastings Triplet Loupe to magnify images with accurate color, in sharp focus over the entire lens.
Actually, three separate lenses are bonded together to form a compound lens which virtually eliminates distortion at the outer edges of the magnifier. The compound lens is housed in a black plastic frame which is designed not to reflect light onto the object being viewed. The case is nickel plated and serves both as a handle and as a dust protector.
The Bausch & Lomb Hastings Triplet Loupe is the magnifier of choice for grading diamonds and other gems. In the jewelry trade, it is accepted that a diamond is considered flawless if imperfections cannot be seen at 10X magnification with a Hastings Triplet Loupe.
We sell this loupe in 7X, 10X, 14X and 20X. As the magnification increases, the diameter of the lens decreases. Unless you have already used a Hastings Triplet Magnifier, and you know that you must have 14X or 20X magnification, we strongly suggest that you select the 10X loupe. The 10X is pictured above. The narrow field of vision in the 20X and 14X models is often found to be less comfortable.
