Stage based 2 Dimensional Measurement System

This Vision based 2 D Measurement System combines the measurements from the pre-calibrated image and stage movement as measured by precise linear encoder scales. (The L140EA, EC, ED are all image based measurement systems that measure only within a field of view and the stage provided there is only for the purpose of convenient object movement. )

Stage Based 2 Dimensional Measurement System

The product shown above is “2D Image+Stage Measurement System”. The manually operated Stage has 5 micron LC encoder incorporated on both axes. The measurement precision is of the order of 10 microns. The Stage is also provided with quick traverse levers.

The product uses National Instruments Vision based software named as LenselVision 200.

The product provides a simultaneous optical view through the right eyepiece.

General Specification

  • Camera: 1.3 megapixel digital camera. This camera is optimal for the resolution and data capture.
  • Optics: 0.185X to 1.18 X detent measurement lens. It provides a field of view of 24 mm at 0.7 X setting and 3.5 mm at 4.5 X setting.
  • Magnification: On screen magnification is equivalent to 11X to 70X.
  • Illumination:

    Top LED ring light with intensity control.
    Bottom: Profile light of Diameter 30mm beam for measurement.

  • Optical Magnification: 7Xto 45X.
  • Working Clearance: 125 mm.
  • X-Y Stage: Precision measurement stage with 5 micron LC scales. Manually operated by knobs. Quick traverse levers available to quickly move when not actively measuring. On screen DRO is available to manually note readings if required.
  • Z axis for optical head height is adjustable up to additional 100 mm to accept tall jobs.
  • The system requires a PC with following minimum specification. Dual Core or higher with WinXP or Win7, Free USB2.0 port, 1 GB RAM, 10 GB free HDD Space. Monitor 43 cms.

Optional:

  • Change in magnification range is possible with change of optics.
  • Higher resolution camera, say 3.0 megapixel. However, this slows frame rate.
  • CFL illumination instead of LED Illumination.
  • 1 micron LC Stage in place of 5 micron LC Stage.
  • Any specific customization.
