The UNITRON Z750 Series with a 7.5:1 zoom ratio is an excellent choice for industrial inspection, assembly, quality control, OEM integration, research and education applications requiring a wide magnification range with outstanding optical performance. Apochromatically corrected optics deliver exceptional image clarity and color accuracy across the full zoom range, while a generous working distance of 125mm provides ample room for tools and sample manipulation.
The Z750 Series is a versatile, high performance, ergonomically designed zoom stereo microscope ruggedly built to withstand years of heavy usage.
The Z750 Series is available with either a binocular (coming Fall 2026) or trinocular viewing head (shipping now!). The trinocular model employs a fixed 50:50 light split between the eyepieces and trinocular port.
