Key Features

  • 3.35X-90X extended zoom magnification using high-resolution Greenough stereoscopic objective lenses with 0.5X 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.
  • 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 ZM-4BN matches its sleek design and 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 wide-field eyepieces provide an ample magnification range from 6.7X to 45X, with high-eyepoint optics to accommodate glasses or goggles. 0.5X and 2X Barlow lenses are included, which can be alternated to either halve or double the magnification range, expanding the possible magnifications to 3.35X-90X.

Ocular Adjustment

This model does not have integrated ocular diopters, opting for focusable eyepieces instead. This helps maintain consistent focus when dioptric adjustments are not needed. Locking screws on each ocular tube will prevent rotation when adjusting focusable eyepieces, and stop eyepieces from falling out. Sliding interpupillary adjusters ensure that each user can properly align the eyepieces for comfortable viewing.


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.
