Accessories: SG Series 3D Scanheads

Description

Scanheads Option
We offer a range of 3D scanheads for maximum flexibility. Some of 3D scanheads are built to scan a large area, while others scan smaller areas with greater accuracy.Multiple ShapeGrabber scanheads use a modular design so different scanheads can be swapped in and out of our 3D scanners. This enables customers to scan in a widerrange of resolutions or objects of widely varying sizes.

All ShapeGrabber 3D scanheads feature:
• CDRH Class II / IEC Class 2M Lasers
• IEEE-1394 (Firewire) interfaces
• Industrial design with no moving parts

NEW:- Sixth-Generation Scanhead
The SG156 Scanhead is the newest addition to our 3D scanhead family. This sixth-generation technology is our fastest scanhead to date, with an improved laser, lens,imager, and mounting mechanism. The SG156 features:
• Up to 10 times faster scanning speed than its predecessor
• Variable field of view in addition to depth of field
• Greater accuracy and tolerance to temperature changes
• Larger dynamic sensing range to scan wider range of part types
• A new mounting design allows the SG156 scanhead to be easily installed and removed; and, provides greater precision

ShapeGrabber® 3D Laser Scanner Systems
Industries:
1) 1) Automotive: Injection Molded Plastic Fittings, Dashboard Panels, Radiator Covers, etc
2) Aerospace: From Airframe parts to Engine components, eg Turbine Blades and others
3) Medical: Molded Dental Teeth, Ear Hearing Aids, Prosthetic Devices, etc
4) Plastics: Molded Plastic Cases for machine tools and molded Automotive parts, Electronic Plastic Connectors and any injected Plastic components
5) Precision Engineering: Stamping Parts, Precision Metal Casting, Checking supplier's part meets specifications, etc
The ShapeGrabber 3D laser scanner system uses a non-contact measuring process for 3D quality inspection and measurement that is fast and easy, and able to handle complex shapes.The process can also be used for reverse engineering and product design complementing 3D modeling and CAD systems.
 
  • Colour map comparing metal CAD file to ShapeGrabber's 3D Scan of the metal turbine blade
.
  • Colour map comparing plastic CAD file to ShapeGrabber's 3D Scan of the plastic radiator top cover
    

The system software captures and converts "points cloud" data into images for further analysis in metrology and reverse engineering. Seen here is a plastic cover application for inspection with CAD file.
