Celestron Lab's CB2000CF Compound Binocular Microscope is ideally suited for students and hobbyists with its comfortable binocular head design and broad magnification range. Its four-objective click-stop turret holds the 4x, 10x, 40x, 100x achromatic objectives and the instrument comes with two sets of eyepieces that produce magnifications from a practical 40x to a powerful 2000x. The 4.3x4.7" stage is articulated on the X and Y axes to place the exact area of interest precisely in the centre of the stage. An adjustable-intensity halogen bulb under the stage provides the necessary illumination and the manually adjustable iris and Abbe condenser ensures the perfect amount of light and beam spread to illuminate the specimen without washing it out. Use the coarse and fine focus knobs, and the right-eye dioptric adjustment, to bring all specimens into sharp, clear focus.
