The standards set by the SZ61 and SZ51 are a revelation. The "Comfort View" eyepiece design and the accessible, responsive controls make operation easier and less fatiguing than ever before. The compact design, incorporating the Greenough optical system, delivers excellent flatness and ample depth of field as well as clarity, detail, and accurate color. Dependable, high-performance optics are central to the production of consistent, accurate results in today's widening range of biological microscopy applications-as are ergonomic features which make even long-duration tasks easier and less demanding to perform.
