The microscope for looking at things, not through them
Stereoscopic microscope, 20x magnification. 10x wide field eyepieces with 2x objectives, dual light sources, inclined body, cast aluminium. 12V 10W incandescent illumination.
A stereo microscope does the job a compound microscope cannot: it looks at the surface of a solid object, with both eyes, in three dimensions. A beetle's leg, a seed head, a crystal, a circuit board, a coin, a piece of bark. The specimen sits on the stage as it is - no slide, no sectioning, no preparation at all.
Dual light sources are the reason to buy this one. Light from above shows surface texture and colour. Light from below shows outline and anything translucent. Being able to switch between them, or use both, is what makes a stereo microscope useful rather than just bright.
20x is the right power for this job. Higher magnification on a solid object gives you a shallow depth of field and a confused student.
Cast aluminium body and an inclined head, which means it survives a school and does not give students a sore neck. It uses an incandescent globe rather than LED - warmer light, and a globe that will eventually need replacing.
