SZ650/680/SZ810 Zoom Stereo Microscope for Electronic Industry

SZ650, SZ680, and SZ810 are zoom stereo microscopes from Nanjing AMADA Instrument Co., Ltd. designed for electronics assembly, PCB inspection, and precision bench work. The series provides zoom ratios of 1:6.5, 1:6.8, and 1:8.1 with a 110 mm working distance on the built-in 1X objective path, optional video output, and multiple illumination choices including LED, halogen, and cold light source (100V–240V).

  • Three models (SZ650 / SZ680 / SZ810) allow selection based on zoom ratio, field diameter, and viewing angle requirements
  • 110 mm working distance on the standard 1X path for unobstructed access during soldering and component handling
  • Optional trinocular and video output paths with configurable light distribution (100% or 50:50) for documentation and inspection
  • Wide voltage input (100V–240V) supports global use without power conversion
  • Adjustable interpupillary distance (50–75 mm) and stereo angle (12°) for ergonomic viewing
  • User-selectable zoom range limits to match specific inspection tasks

Use guide

  • Select the model based on required zoom ratio, field diameter, and viewing angle
  • Choose 0.5X additional objective when more working distance (189 mm) is needed for tall fixtures
  • Use 2X objective when high magnification is required and working distance is not a constraint
  • Add trinocular or video output path when documentation or live imaging is required
  • Select stand type (pillar or guide rail) based on available workspace and focusing distance needs
