Condenser:: Condenser: 1.25 Abbe

A n-ew standard of precision optics, highly engineered mechanics and very rugged construction, all at a 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 rechargeable LED illumination system provides optimum image brightness, virtually no bulb heat and has a 50,000-hour rated bulb life.
