Greenough Optical System
The 10-degree angle of convergence in the Greenough optical system secures excellent image flatness with large depth of field. The careful selection of lens surface coatings and glass materials in the entire optical system makes it possible to observe and document specimens in their original, authentic colors. The V-shape optical path achieves a slim zoom body – suitable for integration into other equipment or standalone use.
Wide Zoom Ratio
The SZ61’s magnification range extends from 6.7x to 45x (using 10x eyepieces), with a wide zoom ratio of 6.7:1, enabling smooth, macro-to-micro zooming that speeds routine workflows. The SZ51 provides the magnification rage of 8x to 40x (using 10x eyepieces), with a wide zoom ratio of 5:1.
The suitable inward angle allows just the right combination of high level flatness and depth of focus for 3D viewing. Even a specimen with significant depth can be brought into focus from top to bottom for faster inspection.
