ENGINEERED BY CAMBRIDGE TECHNOLOGYAIR BEARING POLYGON SCANNERS

AERODYMANIC AIR BEARINGS PROVIDINGEXCELLENT REPEATABILITY
Novanta develops photonics solutions through our globally
recognized brands— ARGES, Cambridge Technology, Laser
Quantum and Synrad— specializing in cutting-edge components
and sub-systems for laser-based diagnostic, analytical,
micromachining and fine material processing applications.
Powerful lasers, coupled with advanced beam steering andintelligent sub-systems incorporating software and controls,deliver extreme precision and performance, tailored to ourcustomers’ demanding applications.

LONG LIFETIME AND HIGH
REPEATABILITY FOR HIGH-SPEEDRASTER SCANNING
Engineered by Cambridge Technology, our air bearing based
polygon scanners provide excellent repeatability and long lifetime
due to no bearing wear while the scanner is operating.

HIGH PERFORMANCE AND LONGSCANNER LIFE

Our aerodynamic air bearings have been developed to withstandover 20,000 start/stop cycles. They generate their own air pressure
as they rotate and require no external air pressure support
equipment to operate.

•Speeds ranging from 6,000 to 55,000 RPM for aerodynamicscanners and from 0 to 30,000 RPM for aerostatic scanners•

Excellent scanner life due to minimal contact between
bearing components•

High repeatability and tight dynamic tracking•

DC brushless motor designs offer superior operating
characteristics in the most frequently specified speed ranges
with high efficiency, high torque output, and excellent
positional accuracy.

•

Enhanced aluminum and protected gold coatings covering
wavelengths from 350 nm to 10,600 nm•

Polygon facets down to 1/8 wave flatness and 60/40 surfacequality•

Excellent power handling due to high rotation speeds andaluminum polygon substrates

Our aerostatic air bearings provide the ultimate polygon scannerperformance. These use pressurized air and closely spaced bearing
surfaces to float the rotor. When pressurized, the bearing has
no contacting parts which results in extremely long bearing life.
These bearings are very stiff and have wobble errors less than one
arcsecond.
