Olympus CX31 Binocular Biological Microscope

The Olympus CX31 Binocular Biological Microscope is a professional laboratory microscope designed for routine brightfield microscopy in clinical, medical, educational and research laboratories. The CX31 uses Olympus' UIS2 Universal Infinity-Corrected optical system, providing high-quality optical performance for routine specimen observation. It incorporates a binocular observation head, mechanical stage, Abbe condenser and built-in transmitted illumination. A commonly supplied CX31 configuration includes 10X eyepieces and Plan 4X, 10X, 40X and 100X oil-immersion objectives, giving total magnifications of approximately 40X, 100X, 400X and 1000X. Exact objectives supplied should be confirmed from the individual unit because configurations can vary. The microscope is suitable for examining prepared biological specimens and can be used in hospital laboratories, diagnostic laboratories, universities, schools, research institutions and other laboratory environments.
