Greenough Based Optical System

Applications

The Greenough optical system of the Leica StereoZoom® line consists of two image paths converging at 12°. The lens pairs of each optical path are positioned closely together, giving the stereomicroscopes a very "slender" design, especially toward the base of the instrument. This design offers the advantages of accommodating a small space requirement for use on bonders and in machine applications. Other advantages of this system include unobstructed specimen access which allows plenty of space for tools and a completely free view of the sample during initial positioning. The Greenough system permits cost-effective correction of aberrations, such as chromasia, image field curvature and distortion. The new Leica StereoZoom® line uses the most corrected area of each lens, the center, for image production. This provides superior optical performance with large, level, undistorted fields of view and chromatically optimized, high-contrast images.
