Galvo Series: Closed Loop with
Moving Coil Capacitive Front End Position Detector
Galvanometer Models:
6350 | 6400 | 6450
| 6650 | 6900
The Moving Coil Closed Loop Galvanometer
series combines Cambridge Technology's moving coil actuator technology and
our patented moving dielectric capacitive position detector design. This
combination offers the highest position accuracy and repeatability of any
galvanometer based scanner design. These scanning systems can be designed and
optimized for speed, size, cost and accuracy with typical beam diameters of 5
mm - 75 mm.
Features
- Highest Position Accuracy
and Repeatability: The moving coil's superior positioning accuracy
comes from the actuator design configuration and patented position
detector design. The scanner's front end position detector provides the
closest coupling between the mirror and the position detector for the
truest positioning. CTI's moving dielectric
capacitive position detector is designed to provide superior
repeatability and positioning linearity over time and temperature. This
capacitive detector, with CTI's 671 servo
driver, reduces the optical positioning error, thus allowing single microradian level positioning performance as low as
1.5 microradians.
- Galvo Speeds and Step
Response Times: The high torque to inertia ratio of the moving coil
design allows for the high positioning speed of the galvo series. The
intense magnetic field strength of state of the art neodymium iron boron
magnets combined with the low rotor inertia of the moving coil design
gives the moving coil galvo very high torque to inertia ratio for high
peak and RMS accelerations with excellent wobble and jitter performance.
Our advanced actuator design coupled with our 671 servo drivers, allow
the moving coil galvos to reach speeds up to 1 kHz with step response
times in the 1.5 millisecond range for small angle movements.
- High System Performance and
Reliability Over Time: Superior product lifetime and reliability result
from disciplined design technique, the best in bearing technology and
quality manufacturing processes and workmanship. Cambridge Technology's
high standards of manufacturing quality guarantees the performance
consistency that you need to design the high quality systems demanded in
today's competitive marketplace.
