GALVANOMETRIC  SCANNERS (GALVOS)

The LSS galvanometric scanner is a limited rotation device designed to position a light beam according to the magnitude of the applied command signal. The scanner uses a highly efficient 4-pole moving magnet  motor technology. Its high torque-to-inertia characteristic permits fast dynamic response. The  fixed stator winding architecture of the motor  is a key component to its unparalleled reliability.

The scanner incorporates a state of the art electro-optic position sensor for highly accurate beam positioning using a servo amplifier. The position signal voltage is proportional to the tangent of the scan angle, which linearizes the signal for flat field scanning applications.

LSS uses the Measurement and Certification Techniques to guarantee that every  scanner performs to laid specifications. Each scanner is tested and “burnt in” for 24 hours prior to shipment, to ensure reliability.

Key advantages of Galvanometric Scanners:
o   Very fast step response times
o   High consistency and stability
o   Low current, low heat generation
o   Ease of tuning and system integration
o   Auto. compensation for manufacturing variations

Some applications:
o   Material processing
o   Rapid prototyping
o   I.R. Imaging
o   Laser projections (for Laser Light Shows etc.)
o   Raster Scanning  (high duty saw tooth scanning).

Galvanometric Scanners (Series  LBS-6000) features:
• Patented 4-pole moving magnet technology
• Optimized for loads up to 5gm cm2
• Wide angles, up to 50° optical
• High bandwidth electro-optic position sensor with integrated temperature compensation
• Dimensions: 30 mm dia. x 75 mm length.
