OLYMPUS CX-21 BIOLOGICAL MICROSCOPE

The Olympus CX21 are designed for long-term use. To minimize the danger of parts getting lost or damaged during transport, the eyepiece, objectives and condenser are all factory-attached to the body, and the revolving nosepiece is firmly fixed to the wide, rigid arm. An anti-fungus treatment is applied to the objectives, eyepieces and observation tube to help assure consistent image clarity and long operating life even in hot, humid working condition. Both models offer excellent basic performance and reliability. For environmentally friendly performance and reduced running costs, the CX21LED reduces the need for frequent lamp replacement by using a light-emitting diode ( LED) with a lifetime of approximately 20, 000 hours. A mirror unit is available as an optional accessory, allowing either model to be used in locations without access to electrical power. The rackless stage helps prevent accidental hand injury, and offers reliable, abrasion-resistant operation for smooth, continuous stage movement. A mechanical stage focus-lock prevents accidental contact with the specimen and makes it easy to refocus when the specimen is changed.
