A real compound microscope, scaled for a junior classroom
Monocular compound microscope. 10x eyepiece with 4x, 10x and 40x objectives, giving 40x, 100x and 400x. LED illumination, disc diaphragm, coarse focus. 160 x 114 x 310mm.
The distinction that matters when you are buying: this is a compound microscope, so it looks through thin specimens on a slide - onion cells, pond water, a cross-section of a leaf. It is not the one for looking at a beetle or a coin. That is the stereo microscope, which is a different instrument for a different job.
At 400x students can see individual plant cells and their nuclei, which is the point at which biology stops being a diagram in a book.
Why the junior model rather than a full lab microscope: coarse focus only, so a student cannot lose the image chasing a fine adjustment; LED rather than a mirror or a hot bulb; and a base heavy enough that it does not walk across the bench. It is compact enough to store thirty of them, which is what makes a class set realistic.
Buy prepared slides with it - a first lesson with a microscope and nothing to look at is a wasted lesson.
