Infrared Imaging : The best gets better
Viewing infrared wavelengths between 0.4-1.5microns, the converted image produced by the new 7215 is now brighter and offers edge to edge sharpness.
What sets the PiezoMove products apart are the internal flexure guides which make additional bearings or guidance mechanisms obsolete when integrating them into a nanopositioning system.
Three versions are available providing up to 480um of travel.
Piezo actuators can move in subnanometre increments, however, open-loop devices do not provide linearity or repeatability.
PiezoMove actuators are available with integrated absolute measuring position sensor permitting closed-loop operation with 99.8% linearity and nanometre repeatability.
The stiff design leads to high resonant frequencies of 750Hz allowing settling times of only a few milliseconds, ideal for highly dynamic applications.
Reliability is assured by the use of award winning PICMA actuators in a sophisticated single module flexure guidance system.
PICMA actuators feature ceramic encapsulation thus offering better performance and reliability than conventional actuators.
The wire-cut flexures are FEA modelled making them extremely precise and not subject to wear, leading to maintenance free operation. Request a free brochure from Lambda Photometrics ...
