Biological microscopes (compound microscopes) provide high-contrast, transmitted-light imaging of thin specimens such as cells, tissues, and microorganisms. Typical configurations include binocular or trinocular heads, LED illumination with Köhler or field diaphragms, plan or achromat objectives, and a mechanical stage for precise slide movement. Options such as phase contrast, polarisation, and camera ports support teaching, clinical diagnostics, and routine laboratory work.
