The "Linen Tester" is a convenient foldable magnifying glass for inspecting fabrics and printed materials. It features a 50mm & 2-inch scale, 4x magnification, and double lenses.
A linen tester is a magnifying glass originally designed to inspect the weaving of fibers (linen), but it is also convenient for quickly inspecting flat items (such as printed materials). It can be folded small, making it a portable magnifying glass for simple inspections of flat objects, which we recommend for those looking for such a tool. The scale has two sides with millimeter markings and two sides with inch markings. The millimeter scale is in 1 mm increments, while the inch scale is in 1/8 inch increments.
[Difference between single lens and double lens]
Compared to a single lens, a double lens reduces distortion around the edges. When you bring your eye close to the lens, there is not much difference, but as you move your eye away, the difference becomes apparent.
