Working Principle
The BM–4 microscope directs light from the arc-reflector through the condenser onto the specimen. The objectives magnify the image, and the wide-field eyepiece enlarges it for observation. Users adjust focus using coarse and fine knobs while positioning the slide on the stage. The Abbe condenser and iris diaphragm allow precise control of illumination and contrast, producing bright, sharp, and clear images ideal for student learning and laboratory experiments.
