Achromatic objectives equip the LCD Digital Microscope II with an optical system that transmits enhanced contrast and minimal image distortion. The objective turret features 4x, 10x, and 40x color-coded objectives capable of up to 160x, 400x, and 1600x magnification using digital zoom. This microscope also provides variable-intensity top and bottom illumination, both controlled by a base-mounted dimmer wheel. Complementing the bottom LED light source, a condenser lens and disc diaphragm with color filters provide several options for specimen illumination. To enable fine control of the specimen, the LCD Digital Microscope II is configured with a mechanical stage, making this optical-electrical instrument ready for the lab as well as the classroom.
