Carl Zeiss's Stereo Discovery range of stereomicroscopes can be transformed into a single-channel zoom microscope with a coded, three-position nosepiece and motorised Y intermediate tube.
On the Stereo Discovery V20, a continuously variable magnification range of up to 233:1 is said to provide users with high-quality, 3D images, convenient binocular observation at maximum resolution, and parallax-free documentation over the entire magnification range.
The company said fast and reliable zooming into object details with a structure width of up to 0.5 micrometres is possible from low-power magnifications with a field diameter of up to 11mm.
The Parfocality Manager ensures that the microscope image always remains exactly in focus, even after a change of objective.
Furthermore, beam delivery of the overall system is automatically adjusted on the nosepiece after the change between stereo observation and parallax-free, single-channel vertical observation.
This guarantees permanent binocular observation in both 3D and 2D, according to Carl Zeiss.
These changes will be of interest to users in industrial production control and quality assurance where inspection, documentation and the measurement of structures and components are part of everyday routine and speed and precision are highly valued.
Other improvements in the Stereo Discovery have also been implemented.
The ring illuminators developed for the nosepiece ensure consistent reflected-light illumination without annoying cables and light guides and the system's light manager function automatically adapts the brightness to the magnification used.
Equipped with the Axiocam digital microscope camera and the Axiovision software, the Stereo DiscoveryV20 is well suited for observation and the professional documentation of materials and components.
