AmScope SM-4B Series Binocular Zoom Stereo Microscope 3.5X-180X Magnification with 80 LED Compact Ring Light on Double Arm Boom Stand
Key Features
- 3.5X-180X extended zoom magnification using high-quality Greenough stereoscopic objective lenses with 10X and 20X eyepieces, and 0.5X and 2X Barlow lenses.
- The microscope provides up to 6.5" (165mm) of working distance.
- A highly-versatile stereo microscope on a heavy-duty, multi-pivot boom-stand which allows the microscope to easily swing into place when needed, and away when not.
- 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 80-LED ring-light produces an encompassing field of bright light with reduced shadows for use with any application.
The SM-4B is a heavy-duty, highly-flexible microscope designed for biological and industrial applications. This model is especially popular in the QC, repair and engraving industries thanks to its ease-of-use and reliability. With its wide zoom range and double-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 and 20X eyepieces are included, as well as 0.5X and 2X Barlow lenses to provide an expanded magnification range from 3.5X-180X, 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.
Double-arm Boom-Stand
The multi-pivoting, double-arm stand provides a stable, flexible support system, ideal for hands-on work. Use of a drop-down column allows the head to be positioned at virtually any angle. Ball-bearings provide smooth movement of the lateral arms, which can easily pivot the microscope out of the way when it is not needed. The heavy, steel base ensures the stability of the microscope, even when laden with attachments.
Additional Items
This package includes an 80-LED ring-light for bright and cool illumination. This lightweight illuminator mounts to the microscope’s objective housing, and projects an encompassing field of light over objects, eliminating most shadows. Whether used as the sole light-source or in combination with additional illuminators, the ring-light produces a crucial light pattern for virtually any application. Energy-efficient and producing low heat, this ring-light can be used with biological specimens as well as industrial.
