Olympus CX33 Trinocular Biological Microscope – LED

The Olympus CX33 Biological Microscope is a professional upright microscope designed for comfortable and efficient routine microscopy in clinical, laboratory, research and educational environments. The CX33 uses an infinity-corrected optical system, Plan Achromat objectives and transmitted Köhler LED illumination to provide clear, flat and evenly illuminated specimen images. Unlike the CX23, the CX33 incorporates a trinocular observation tube, enabling visual observation through the eyepieces as well as connection of a compatible microscope camera for digital imaging. Its light path can be switched between 100% eyepiece observation and 100% camera output. The ergonomic design places the focusing and stage controls within comfortable reach, helping reduce unnecessary movement during prolonged routine laboratory work. Evident specifically positions the CX33 for comfortable, high-throughput routine microscopy.
