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.
PI's steering mirrors use a parallel-kinematic design with a single moving platform and coplanar rotational axes providing jitter-free multi-axis motion.
In addition, the single pivot point design gives better linearity and overcomes the problem of polarisation rotation commonly found in galvo scanners where two single axis scanners must be stacked to provide x-y motion.
Compared with stacked x-y systems, PI's design provides faster response offering equal dynamics for all axes in a smaller package.
Flexure guided, piezo driven platforms provide higher acceleration than voice coil actuators with step times in the submillisecond range.
Integrated absolute position measurement sensors feed information back to a piezo controller for improved linearity and stability.
A range of analogue and digital controllers in benchtop, OEM-board and rack-mounted designs is available.
The new high speed steering mirrors will improve the performance of optics and imaging systems in a variety of applications ranging from lithography to biomedical instrumentation. Request a free brochure from Lambda Photometrics ...
