The ME10 Series beginner microscope uses a prism to reflect natural light to allow users to examine minerals, stones, insects, flowers, pond water, slides and other objects. This light gathering prism can collect ambient light from the room and conducts the light up the optical path of the microscope. The optical prism provides cool even lighting without the need for adjustment. This microscope is constructed with an all-metal frame and a round movable stage to allow easy control of specimens. Choose between a 5x and 10x wide-field eyepiece with pointer and either a 4X or 10x DIN objective. It provides a total magnification of 20X, 40X or 100X. These models are suitable for grades K-6.
