SM-3B Binocular Zoom Stereo Microscope 7X-135X Magnification on Single Arm Boom Stand

SM-3B Series Binocular Zoom Stereo Microscope 7X-135X Magnification on Single Arm Boom Stand. The SM-3B is a heavy-duty, highly-flexible microscope designed for biological and industrial applications. This model is especially popular in the QC, dental, repair and engraving industries thanks to its ease-of-use and reliability. With its wide zoom range and single-arm boom-stand, this model will become an indispensable instrument in any workshop or lab. OpticsThe stereo optics provide clear, sharp images with excellent focus-depth and a large working-distance. With 0.7X-4.5X zoom objectives, moving through the magnification range is as easy as turning a knob. 10X and 15X eyepieces are included, as well as a 2X Barlow lens to provide an expanded magnification range from 7X-135X, with high-eyepoint optics to accommodate glasses or goggles. Ocular Adjustment Dual ocular diopters can be adjusted to maintain consistent focus, greatly improving productivity. Rotating interpupillary adjusters simplify the process of aligning the eyepieces for each user. Single-arm Boom-Stand The multi-pivoting stand provides a stable, flexible support system, ideal for hands-on work. The single-arm design provides heavy-duty support in a simple form. The head can be turned 360°, the focus-block can swing in either direction, and the lateral arm can rotate and swing to position the head at virtually any angle. The heavy, steel base ensures the stability of the microscope, even when laden with attachments.
