QVI Cobra (2D/3D) Laser Scanner System


The Cobra is a laser-based system for non-contact surface profile scanning.  Standard features include:

  • Precision mechanical bearing internal Y axis transport providing a total scanning range of 50 mm.
  • Capture range in Z of 0.3, 0.5, 2.0, or 8.0 mm depending on laser sensor selected: DRS 300, 500, 2000, or 8000.
  • Micrometer-adjust Z-axis with 50 mm range for setting laser focus
  • Includes one DRS sensor of choice.  DRS sensors automatically compensate for varying part reflectivity allowing accurate measurements for shining, diffuse, or multi-coloured surfaces
  • Scan-X measurement analysis software provides 2D, high resolution measurements of height, length, area,
    slope, radius and surface roughness.  Includes full language support.
  • For applications such as solder paste, coatings, seams, seals, film, rivets, membranes, etc.
  • Easy connection to customer supplied computer through parallel port (no interface cards required).
  • Operations manual and on-line help functions.
