First, a 10x lens is the most poplular and best power for a handheld magnifier. The BelOMO 20x 17.5mm (0.50'') Qaudruplet Loupe Magnifier has a viewing area of 0.28" (7mm), much larger than the Bausch & Lomb Hastings Triplet Magnifier. The 4 elements making up this quadruplet provide a bright, and clear view. The housing and cover are coated with a matte black finish and assembled using flathead screws. Belarusian Optical and Mechanical Association (BelOMA), makers of sights for guided weaponry, camera lenses, and other optical components manufacuturs these loupes. The high quality optical lens of each loupe is tested and certified, just like a camera lens. The 20x power magnification provides the strongest magnification recommended in a hand held magnifier. While all 20x power magnifiers provide LOTS of magnification you'll find depth of field (that amount of vertical relief that appears in focus) very small making this much magnification hard to use. That's a trade off and why we seldom recommend so much magnification unless you have a specific need. Imagine viewing an example quarter that's 20'' wide and you're looking at it through a 1/4 inch in diameter hole. Now the quarter is 20'' wide but you can only see 1/4 inch at a time. That's a 20x power loupe. !!!!!!!!!!!! WARNING: EXTREME MAGNIFICATION. LIMITED DEPTH OF FIELD. MUST HOLD AT THE EYE SO IT ALMOST TOUCHES. OBJECT MUST BE WITHIN 3/8 INCH OF FRONT OF LENS. HOLD "MADE IN BELARUS" SIDE TO EYE. !!!!!!!!!!
