The 106-LED Compound Microscope from National Optical is a three-objective intro-level microscope designed for elementary school students. Achromatic eyepiece and objectives minimize image distortions and deliver consistent images on all three magnification settings. The user-friendly microscope design has dual coarse-focusing knobs and features that are intended to prevent mishandling by novice users. National Optical engineered this vertical compound microscope to be easy to use, durable, and feature-rich enough to help transition older elementary school students to more sophisticated microscopes.
