Summary
Uses lenses and visible light to magnify specimens up to about 1500 times.
In depth
Parts: eyepiece, objective lenses (4x, 10x, 40x, 100x oil), stage, condenser and light source. Total magnification = eyepiece × objective. Focus with coarse then fine adjustments. Wet mounts and prepared slides are used.
Use the lowest power first, then focus up. Keep slides flat and clean lenses. Oil immersion requires special lens. Drawings should be clear with labelled lines.
Key idea: contrast and resolution matter as much as magnification.
