Celestron's Professional High Power Compound Biological Binocular Microscope has a large mechanical stage, so there's plenty of space to work. The binocular head rotates 360 degrees and is inclined at 45 degrees; two wide-field eyepieces have eight powers, so you can look at your specimens comfortably and closely. Multi-coated optics with Koehler illumination provide clear, crisp images. Large objective nosepiece is reversed to give you extra room. Coaxial knobs control fine and coarse focusing and the diaphragm lets in just the right amount of light. Includes five prepared slides.
