Representing the very best of our Zoom Microscopes, the PZ4 Series uses a parallel optical design that gives users a clear sharp image with genuine color throughout the field of view.

Stereo viewing angle is larger for accurately positioning and operating the specimens, while extending focusing point to reduce eyestrains.

Highly modular design, easily upgradable. Simply transform your existing Binocular setup to an imaging system by attaching a Trinocular Image Port!

Wide magnification range, capable of wide range from 2.4X - 320X, depending on optical accessories.
