The SZ61 and SZ51 new ComfortView eyepieces ensure fast, comfortable observation with the advantage of pupil aberration control, while the universal LED illumination stand brings together all the advantages of LED technology. The small angle convergence of the image-forming path in the Greenough optical system ensures excellent image flatness and depth of focus. Superior optical coatings provide high color fidelity. Antistatic materials and coatings protect specimens from electrostatic discharge. The SZ61 zoom stereo microscope is ideal for routine and advanced stereo microscopic observation, especially when documentation with digital imaging is required. The cost-efficient SZ51 zoom stereo microscope offers a broad range of functions for life sciences.
