10x handy magnifying glass (diameter 30mm)

10x magnification hand-held magnifier with compound lens. The built-in illumination is a simple incandescent lamp, which requires 2 Baby batteries (LR14, size C), not included.

Compound loupes differ from simple loupes in that they contain both an objective lens and an eyepiece lens, allowing higher magnification and better image quality than with simple magnifiers. At the same time, the large magnification reduces the lens size, but makes these loupes easy to carry in the hand or pocket, making them absolutely portable, even in the field. They can also be called hand-held microscopes, as their built-in illumination and magnification range make them closer to small stereomicroscopes than to hand-held magnifiers.
