RS2 Scanner TechnologyRS2 Scanner Technology

How does RS2 work?

• Project a flat plane of tuned laser light

• Capture the reflection from the object with a 2D camera

• Extract the line from the image


RS2 BenefitsRS2 Benefits

• Fully integrated with arm wrist

• Laser power teach function for different colors,

• Semi- Automatic laser control

– Able to scan multicolor parts in one pass

– High tolerance to ambient light

• Small triangulation angle (24 degrees)

– Able to access narrow cavities in complex parts

• Ability to scan difficult materials like carbon fibre

• Contact probing also possible using the arm
