This is a perfect microscope for students to learn science. It comes with full optical glass elements, metal framework, a 360 degree rotatable monocular head, coarse and fine focusing, with an LED illumination system that uses either an outlet (adapter included) or three AA batteries. It offers five magnification settings, 40X, 100X, 250X, 400X, and 1000X. This is an ideal microscope for academics in home school and from students in elementary to high school. A microscope of this caliber is an excellent instrument for hobbyists. Along with some prepared biological-specimen slides, this kit also includes a slide-preparation kit, with blank slides, red and blue stains, and several tools to put together your own specimen slides. There's also a handy cleaning kit for keeping your microscope clean.
