Model 157

A new standard of precision optics, highly engineered mechanics and very rugged construction, all at little more cost than a budget microscope. Objective turret (nosepiece) is in reverse position to permit easier changing and positioning of specimen slides. Preferred by teachers, the 5-watt fluorescent illumination system provides optimum image brightness, virtually no bulb heat and has a 10,000-hour rated bulb life.
