The BelOMO 10x21mm(.85") triplet loupe magnifier has a viewing area of 0.65 inch (17mm), much larger than the Bausch & Lomb Hastings Triplet Magnifier. The 3 elements making up this achromatic triplet provide a bright and clear view. The 10x power magnification provides the best magnification to depth of field ratio and is the most popular power for a hand held magnifier. The housing and cover are machined metal and coated with a matte black finish and assembled using flathead screws. Belorussian Optical and Mechanical Association (BelOMA), makers of sights for guided weaponry, camera lenses, and other optical components manufacturers these loupes.
We highly recommend this loupe. This is the lens we use all the time.
Each BelOMO loupe we ship is custom treated to prevent the screws from coming loose with usage.
Inside the front cover, Robert Hutchinson writes:
It began innocently enough. While photographing the Painted Desert, Atkinson became intrigued with the brilliant colors in the petrified wood scattered on the ground. He brought home some polished rocks, photographed them under glare-free lighting, and was captivated. The photographs looked more like paintings of forgotten dreams than either rocks or photographs. Atkinson proceeded to photograph thousands of art-quality polished rocks, bought or borrowed from international dealers and collectors, and to refine his photographic techniques.
From these thousands of photographs, Atkinson has chosen for ?Within the Stone÷ seventy-two that have yielded the most striking, the most poetic, and the most ineffable images. Atkinson opens a vault beneath our feet, revealing to our astonished eyes the tumult of color, form, and desire hidden ?Within the Stone.÷ He invites us to enter the dreams of Gaia. Some of these are epiphanies so far removed from our mundane experience as to beggar ordinary language and analogy.
Seventy literary pieces were commissioned for this book from seven writers. Every one of the writers has conspicuous attainments in both scientific and artistic modes. Each writer was asked to free-associate with his or her ten assigned photographs as though they were high-level Rorschach patterns. The seven contributors are Diane Ackerman (poet and psychologist), Philip Ball ( Nature editor and dramatist), John Horgan (science writer and philosopher), Andrew Revkin ( New York Times reporter and Hollywood screenplay writer), Dorion Sagan (science writer and novelist), Tyler Volk (NASA biologist and architect), and David Zindell (science fiction novelist and mathematician).
In an appendix, mineralogy experts Si & Ann Frazier and Robert Hutchinson provide mineral commentary for each specimen.

Heavy duty 3/4'' plain black nylon loupe lanyard with a quick release buckle and a split ring. This lanyard may be used for any purpose but we've had it custom manufactured specifically for use with the BelOMO loupe.
Important: We offer this lanyard for no additional charge when you buy the combo package of the BelOMO loupe with attached lanyard. Attaching the lanyard requires a screw to be removed so let us do it. We've been doing it for years and you save money!
Use the split ring on loupes with a mounting hook. To use the lanyard with a BelOMO loupe remove one screw on the support shaft of your BelOMO loupe, swivel the frame out of the way and slide the end over the support shaft then install the screw again. Don't use the split ring to attach the lanyard to the loupe. (We suggest that you purchase the loupe with the lanyard already installed.)
