Z645 Zoom Stereo Microscope Series

The UNITRON Z645 Series with a 6.7:1 zoom ratio is an excellent choice for industrial inspection, assembly, quality control, OEM integration, research and education applications requiring a higher magnification range. Locks on the zoom knobs allow for rapid and repeatable changes between magnifications for consistency in observation.

The Z645 Series is a versatile, high performance, ergonomically designed zoom stereo microscope ruggedly built to withstand years of heavy usage.

The Z645 Series is available with either a binocular or trinocular viewing head. The trinocular model employs a fixed 50:50 light split between the eyepieces and trinocular port.
