107JA Measurement microscopeDetailed product description：

Product Introduction:
107JA is a small precision measuring instrument with grating digital display. In addition to moving the X and Y coordinates, the workbench can also rotate 360 degrees and measure the Z coordinate in the height direction; Observe with binoculars. The lighting system can also provide oblique lighting in addition to transparent and reflective lighting. The measuring microscope can be connected to a CCD television camera to magnify the contour of the workpiece; It can also be connected to a computer for data processing and measurement. It is an ideal multi-purpose small precision measuring instrument.
Measurement microscope 107JA is used to accurately measure the length and angle of the workpiece through transmission and reflection. Specially suitable for testing video heads, line widths of large-scale integrated circuits, and other precision components. Widely applicable to metrology rooms, production lines, and scientific research departments.
