Zeiss Zoom Optics
The Discovery is built with Zeiss world-class, high resolution, apochromatically corrected optics.
The Discovery zoom optics factor is a 20:1 ratio, with a primary magnification range from 7.5x to 148x (with the 1.0x objective), an unparalleled feature in zoom comparison microscopes. The system's unique, synchronized, pancratic zoom bodies ensure the highest degree of magnification reproducibility at over 900 matched magnification set points (with the 1.0x objective) providing high-contrast, in-focus images throughout the entire zoom range. The Discovery produces an erect, un-reversed image with a large Field Number (FN) eyepiece at 23mm. This provides a large field of view and is 9.3% larger than a 22mm FN eyepiece.
