The Leica EZ4 school microscope (incident 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 replacements. The LED lighting offers seven different illumination scenarios with reflected, oblique, and transmitted light, allowing the lighting conditions and contrast to be adjusted to nearly any specimen. The Greenough system provides a vivid, three-dimensional view. The bright LED lighting saves time and costs, as lamp changes are no longer necessary. The 4.4:1 zoom offers crystal-clear magnification between 8× and 35×. The optical Greenough system ensures a vivid 3D representation.
