ENGINEERED BY CAMBRIDGE TECHNOLOGYCRS SERIES, RESONANT SCANNERS

RESONANT SCANNERS FOR HIGH SPEEDIMAGING APPLICATIONS
Novanta develops photonics solutions through ourglobally recognized brands— ARGES, Cambridge
Technology, Laser Quantum and Synrad— specializing
in cutting-edge components and sub-systems forlaser-based diagnostic, analytical, micromachining andfine material processing applications. Powerful lasers,
coupled with advanced beam steering and intelligent
sub-systems incorporating software and controls, deliver
extreme precision and performance, tailored to ourcustomers’ demanding applications.

RAPID SCANNING RATESEngineered by Cambridge Technology, our CRS Seriesof novel resonant scanners are ideally suited for highspeed imaging in real time. The CRS oscillates at a fixed,resonant frequency with a sinusoidal waveform; thisunique scanner design enables a rapid scanning rate.
The mirror is engineered out of lightweight beryllium,
and broadband coatings reflect a wide range of laser
wavelengths. When paired with a galvanometer, theCRS enables high-speed raster scanning over a twodimensional field and is well-suited for microscopy andscanning laser ophthalmology applications.
