Olympus CX22 Binocular Biological Microscope Plan Objectives 4x-100x Used

The Olympus CX22RFS1 is a robust and reliable compound microscope engineered for rigorous clinical, educational, and routine laboratory environments. Utilizing the renowned Olympus Infinity Optical System, this unit is equipped with a full suite of Plan objectives (4x, 10x, 40x, 100x Oil) to deliver exceptional image flatness and contrast across the entire field of view. The built-in 6V/20W halogen illumination system provides bright, adjustable light with faithful color reproduction, essential for accurate cellular and biological observation. Designed with an ergonomic Siedentopf binocular head and a wire-driven mechanical stage, the CX22RFS1 ensures viewing comfort, durability, and smooth operation during extended laboratory sessions.

Condition Used/Inspected. Please note: This microscope is a used item. It has been meticulously inspected and tested by our technicians to ensure full mechanical and optical functionality. The coaxial focusing mechanism operates smoothly, and the halogen illumination system is bright and responsive. Cosmetically, the unit is in good condition but shows standard signs of prior laboratory wear. The included Olympus Plan objectives have been visually verified; the lenses are clear, featuring an intact anti-fungal coating with no scratches or fungal growth that would affect optical clarity.
