CT Series Optical Scanners
 
  • The combination of our Moving Magnet Actuator technology and our innovative patented Advanced Optical Position Detector design offers the highest positioning speed and excellent accuracy in the smallest, lower cost closed loop galvanometers. Scanning system applications can be designed and optimized for speed, size, cost and accuracy with typical beam diameters in the 1 to 3mm range.
  • The Moving Magnet Scanner's Positioning Speed comes from advanced galvanometer and actuator design for the highest system resonant frequency and RMS power capability. The higher resonant frequency of our moving magnet actuator design, the intense magnetic field strength of state of the art neodymium-iron-boron magnets and our advanced servo driver options allow superior system bandwidths, step response times and repetition rates with excellent wobble and jitter performance.
  • Our newly patented advanced optical position detector design coupled with the positioning precision of the moving magnet actuator provides excellent repeatability and accuracy . The advanced optical position detector is designed to provide high positioning linearity, repeatability and stability over time and temperature, and lower closed loop galvo cost in the smallest, most compact package.
  • Superior product lifetime and reliability result from disciplined design technique, the best in bearing technology and quality manufacturing processes and workmanship. We take great pride in the performance of our products. Our scanner designs are computer modeled and have been life-test proven to billions of cycles of operation. Our high standards of manufacturing quality guarantees the performance consistency that you need to design the high quality systems demanded in today's competitive marketplace.

Recommend Galvanometers according to Beam Apertures

 

We have the widest range of galvos available in the market giving our customers the flexibility to select a galvo to optimize price, performance, and footprint requirements of their application.  Each galvo model, although ideally suited for a particular aperture, will also operate mirror sets larger and smaller than the optimum mirror set.   In some applications, the user may choose to implement a smaller, less expensive galvo to operate a larger mirror set as a cost-saving strategy while other users may opt for a galvo with "undersized" mirrors to maximize the rotor stiffness for positioning performance considerations.  The chart below lists the popular range of mirror apertures for each galvo model.  Of course, some users also go outside these ranges to fully optimize their application. 

 

 

3mm Beam Aperture Galvanometers
