The National Optical 214-RLED compound monocular microscope features a versatile design that includes cordless battery operation, built-in camera port, and 4-hole objective turret (nosepiece). The objective turret is in reverse position to permit easier changing and positioning of specimen slides. The rechargeable LED illumination system provides optimum image brightness, virtually no bulb heat, and has a 50,000-hour rated bulb life. Batteries allow up to 500 recharges, for a total of 20,000 to 25,000 hours use from a single set of 3 AA rechargeable nickel hydride batteries. Integrated camera port allows for easy installation of a Moticam camera for image capture. C-mount adapter and camera sold separately.
