AmScope SM-3B Series Binocular Zoom Stereo Microscope 7X-90X Magnification on Single Arm Boom Stand
Key Features
- 7X-90X extended zoom magnification using high-quality Greenough stereoscopic objective lenses and a 2X Barlow lens.
- A highly-versatile stereo microscope on a robust single-arm boom-stand which allows the microscope to be positioned at virtually any angle.
- Dual diopters can be adjusted to maintain consistent focus throughout the magnification range, greatly improving productivity.
- The stereo optics provide upright images with clear depth-of-field and a wide view for hands-on applications.
- This microscope is ideal for laboratories, repair shops, and engravers.
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.
Optics
The 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 wide-field eyepieces provide an ample magnification range from 7X to 45X, with high-eyepoint optics to accommodate glasses or goggles. A 2X Barlow lens is included, which can be mounted to the objective housing to double the magnification range to 14X-90X. This will also result in decreased working distance. The combined magnification ranges provide 7X-90X.
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.
