AmScope ZM-4 Series Professional Extreme Widefield Binocular Stereo Microscope 2X-90X Magnification on Double Arm Boom Stand with Fiber Ring Light
Key Features
- 2X-90X extended zoom magnification using high-resolution Greenough stereoscopic objective lenses with 10X eyepieces, and 0.3X and 2X Barlow lenses.
- High-resolution ZM series optics provide improved sharpness with lower distortion
- 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.
- A 150W halogen illuminator with 35" heavy-duty fiber-optic ring-light provides the smoothest overhead lighting possible. Active cooling and auto-shutoff avoids overheating in strenuous environments.
The ZM-4B matches high-resolution optics with a brawny boom-stand for demanding biological and industrial applications. The ZM series shows improvements in resolution, contrast, and distortion compared to our staple SM series. 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 advanced optical system in the ZM series microscope produces higher resolutions throughout its zoom range, with stunning contrast and color accuracy. The 0.67X-4.5X objective lenses offer excellent focus-depth and a large working-distance, with symmetrical zoom knobs to easily move through magnifications. 10X eyepieces are included, as well as 0.3X and 2X Barlow lenses to provide an expanded magnification range from 2X-90X, with high-eyepoint optics to accommodate glasses or goggles.

Ocular Adjustment
Easy Adjustments for Any User
Dual ocular diopters can be adjusted to maintain consistent focus, greatly improving productivity. Sliding interpupillary adjusters ensure that each user can properly align the eyepieces for comfortable viewing.
Double-arm Boom-Stand
Heavy-duty, Multi-pivoting Support
The multi-pivoting, double-arm stand provides a stable, flexible support system. 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.
Illuminator
Powerful 150W Illumination System with Fiber-optic Ring-light
This package includes a powerful 150W illuminator with a fiber-optic ring-light. The incandescent light-source projects ultra-bright, full-spectrum light which is channeled through the 35†fiber-optic light-guide which provides the smoothest ring of encompassing illumination. The flexible, heavy-duty metal-sheathed guide will hold up to heavy use in your workshop, factory, or lab without worry of crimping or breaking. The light-source is equipped with an active cooling system and an auto-shutoff circuit to avoid overheating in strenuous environments.
