This microscope does not need batteries but uses more natural lighting means, it is perfect for indoor and outdoor use. The base and arm are made of cast alloy with a baked enamel finish; the 10X wide-field eyepiece combines with the 4X objective for 40X magnification. Spring-loaded clips hold specimens in place on the stage, with a sliding barrel focus adjustment, an arm that tilts 45 to 90, and a mounted plastic prism collects light for viewing.
