Carl Zeiss has launched a new multidiscussion system for its Axio Scope and Axio Imager light microscopes. This enables up to 21 observers to view the same object microscopically at the same time. The image generated under the microscope is seen by all observers with an identical image orientation in a 23 mm field of view. The co-observation system is suitable for training and consultation situations, and can be used, for example, in the training of students and for consultation purposes and the joint assessment of difficult cases in medical diagnostics.
