10X magnification, 30mm diameter lens
This one is on an adjustable stand, rather than resting flat over the object, a loupe-on-a-stand. The height and angle of the lens is adjustable. Being on a stand, there is plenty of room to work with tools (within the limits of the working distance, at 10X magnification, being 20mm).
Magnification / lens size in mm: 10X30, officially. The manufacturer's specification is "10X30, but if you measure it carefully, you will find that the visible part of the lens actually measures 27.5mm.
Maximum working distance: 20mm
Origin / brand: we import these from China
Construction / presentation: Jeweller's triplet lens (same as a loupe) on an adjustable metal stand. Supplied in a plain cardboard box.
