XT3A 10/20/30/40X Stereo Microscope for Detection of Surface

XT3A is a stereo microscope from Nanjing AMADA Instrument for surface inspection in electronics, precision assembly, and quality control. It features a 10X–40X magnification range using interchangeable objectives (1X–4X) and wide field eyepieces (WF10X, WF15X, WF20X), with working distances from 55 mm to 81 mm depending on objective. The articulated binocular head, rack and pinion focusing, and arm-type pole stand support flexible positioning and stable operation under bench conditions.

  • 10X–40X magnification range using 1X–4X objectives and WF10X/15X/20X eyepieces for detailed surface inspection
  • Working distance up to 81 mm with 2X objective for handling larger components and fixtures
  • Articulated binocular head with 45° inclination and 55–75 mm interpupillary adjustment for ergonomic viewing
  • Rack and pinion focusing with adjustable torque for consistent focus control
  • Arm-type pole stand with natural light illumination via a 60 mm black-white reversible stage plate

  • Position the arm-type pole stand to align the stage plate with natural light source

FAQ

What magnification range does XT3A support?
10X–40X using any two objectives from 1X, 2X, 3X, 4X and WF10X/15X/20X eyepieces.
What is the working distance with the 2X objective?
81 mm, the highest in the series for handling taller fixtures.
Can I use a different eyepiece?
Yes. WF10X/18mm, WF15X, and WF20X are available as options.
