The Leica EZ4 school microscope (incident light and stereo microscope) with its 4.4:1 zoom is ideal for beginners in microscopy. The subjects of biology, anatomy, and chemistry benefit from the bright, long-lasting LED illumination, which eliminates the need for lamp changes. The LED lighting offers seven different illumination scenarios with reflected, oblique, and transmitted light, allowing the light conditions and contrast to be adjusted for nearly any sample. The Greenough system provides a three-dimensional view with depth perception. Seven different lighting scenarios provide the right light and appropriate contrast for almost all applications. The bright LED illumination saves time and costs, as lamp changes are no longer necessary. The 4.4:1 zoom offers a sharp magnification range from 8× to 35×. The optical Greenough system ensures a vivid 3D representation.
