{Applications / Quality}

A linen tester (also known as a linen prover) is a folding magnifier, traditionally used for measuring the threads-per-inch on linen, which is why it has a scale marked around the base. Today, they are mostly used for viewing stamps, coins, prints and photos - anything flat. They come in all sizes from 15mm to 90mm, one even has a light.

Specifically, this one is large enough to rest over photos, postcards, prints etc, to study details in the picture, it's not too powerful (which would show you the dots that make up the picture).

Not quite what you were looking for? You want a magnifier that rests on the page for reading? We have a few of these, especially designed for the partially-sighted, see our rest-on-page magnifiers
you want a small stand magnifier, but not one that folds? And one that has a high quality lens? See our small stand magnifiers

Too small? Need a stand magnifier that is larger, with space to work under? See our large stand magnifiers (bench magnifiers).

Almost right, but you DO need something considerably more powerful (a large single lens is ALWAYS low-power), AND it must still give stereo vision. Try the type of head-worn magnifier surgeons use. click here. These are good for watch repairing or for work on micro-circuits.

Not good enough?! Need a microscope? click here.
