Description

Greenough The optical system of the Leica StereoZoom® line con- optical system sists of two beam paths converging at 12°. Since the

pairs of objectives are very close together, the stereo- microscopes can be constructed very “slim” towards the base. This has a number of advantages: less space required for use on bonders and machines, unimpeded working on the object, plenty of room for tools, free view of the object field.

The Greenough system provides a low-cost solution for correcting aberrations such as chromatism, curvature of the field of view and distortion. On the new Leica Stereo- Zoom® line the optimally corrected centre of the objec- tive is used for the image. This results in excellent optical performance with large, flat, distortion-free fields of vision and high-contrast images with maximum chromatic correction.

Protection The Leica S4 E, S6 E, S6, S6 D and S8 APO stereomicro- against ESD scopes including cold-light source and stand are made of

antistatic material with a surface resistance of 2⋅1011 ohm/square and a discharge time from 1000V to 100V of under 2 seconds.

The Leica S6 T Terminator for problematical work areas and the T incident-light stand are made of antistatic ma- terial with a surface resistance of 102–106ohm/square and a discharge time from 1000V to zero of under

0.1 seconds.

Photography The Leica StereoZoom® S6 D and S8 APO models are equipped with a built-in video/photo tube that allows for simple, quick setting up of digital, film and analog video cameras.
