Magnifier on adjustable stand, lens is 2X90

Summary

Small table magnifier on horseshoe stand. Adjust it to any position by loosening / tightening the three screws that control the three ball bearings. 

When comparing these magnifiers on the internet always look at the lens size, this is often not stated, making tiny magnifiers look like serious bench magnifiers. See our large large magnifiers on stands.

Magnification, lens size, working distance.

Be aware that lens size, magnification and working distance are connected. This is due to the laws of physics, it is not a choice, this applies to all simple lenses (i.e. not microscopes and telescopes). 

You want the largest lens? A 150mm diameter lens will give a magnification somewhere between about 1.2X and 2X with a working distance somewhere between 250 and 350mm (10 to 14 inches). Ample room to manoeuvre a large object but not very powerful.

You want a powerful lens?  8X magnification will give you a lens of 15 to 25mm in diameter and a working distance of about 25mm (1 inch). 

You want a very large lens with a high magnification? This is not possible with a simple lens.  Consider one of the following: a surgeon’s binocular headband magnifier (it uses two small telescopes not ‘simple’ lenses); a low-power bench microscope (but select the lowest magnification) or a video microscope.
