Step Up To Higher Performance With The Olympus UIS2 Infinity Optics
The CX21 sets new standards for educational and clinical microscope in biological applications
Plan objectives are packaged as standard, providing image flatness that is among the best in this class
The CX21 is equipped with the same UIS2 optical system used in Olympus’ top-level microscopes. In addition, Plan Achromat objectives are included as standard for the first time in this class of microscope, providing sharp images with high contrast right up to the edge of the field of view.

Rackless stage for durability and ease of use

The wire-driven stage movement avoids any protrusion of racks — preventing the possibility of accidental damage or hand injury. Abrasion-resistant rackless design ensures continuous smooth movement.
Component security — Student proof !

The eyepieces, objectives and condenser are all factory attached to the microscope body ensuring that no component is dropped or detached during transportation or regular use.
Ultra-smooth, quadruple revolving nosepiece
High-precision machining ensures smooth operation and durability. Nosepiece includes a rubber ring for an easy ergonomic grip.

Mechanical stage focus-lock prevents mishaps
The focus position can be locked making it easy to refocus when the specimen is changed. With the upper stage position locked, there is no chance of the objective accidentally touching the slide and damaging either the specim en or the objective itself.
Compact design, easy to store and carry
The CX21 is only 391 mm high, compact enough to be stored in a typical classroom cabinet. A cord-rest and wooden storage box are also available as an option, for convenient storage and portability.
Mirror unit allows observation with no power source
Attachment of the optional mirror unit allows observations to be made even when no power source is available. When an external light source is used, the observation head can be reversed and the slide can be viewed through a large opening in the arm
