BelOMO 15x Triplet Loupe Folding Magnifier
The BelOMO 15x Triplet Loupe Magnifier has a viewing area of 0.38" (9mm). The large 12.7mm (.5") 3 elements lens making up this achromatic triplet gathers lots of light to provide a bright, clear, and color correct view. The 15x power magnification provides strong magnification with a fair depth of field ratio. The 15x magnification is much stronger than the most poplular 10x power but not as storng as the BelOMO 20x Quadruplet Loupe Magnifer. But be sure you need this much magnification. for a handheld magnifier without giving up much depth of field. The housing and cover have a matte black finish for gem grading. Belarusian Optical and Mechanical Association (BelOMA), makers of telescopes, camera lenses, and other optical components manufacuturs these loupes. Highly recommended by the Amateur Geologist. This is the lens we use all the time. The BelOMO loupe is a FANTASTIC buy. These are optical quality lenses, each one inspected and certified just like a camera lens, that stand on their own against the higher priced competition. BelOMO loupes are assembled using screws rather than rivets which allows them to be adjusted. Every BelOMO loupe shipped by Amateur Geologist is custom treated to prevent the screws from coming loose with usage. Don't be fooled by cheap loupes selling for nearly the same price of MORE! Many don't even tell the manufacturer. Why? Because they're cheap imports from China, Japan, Tawain or elsewhere which typically cost less than a dollar at import. If you don't know the manufacturer how can you know the quality? Is each lens tested and does it include the certification just like a camera lens? The BelOMO does. Triplet means three lenses made of different types of optical glass bonded together and designed that, together, they straighten out the light that comes into the front of the loupe lens so that it's the same when it leaves. Cheap mport triplets are just three identical pieces of glass, not bonded, that distort the image.
