Product description
The PSD detector uses a "position sensitive device" with a resistive sensor surface for detection. This sensor has no segmentation and provides continuous position information. In contrast to 4-quadrant detectors, the PSD detector thus enables position measurement over the entire detection area.
With the Adjust-In option of the Compact beam stabilization, laser beams can be stabilized at any point on the detection surface. With this feature the PSD detector complements the most commonly used 4QD detector with higher resolution.
By using Invar, a material with a small coefficient of thermal expansion, the high resolution of the detector is permanently maintained.
For easy adjustment of the laser to the sensor, the PSD detector has position and intensity indicators on the back.
A clean room version is also available.
PSD
- Fast position measurement
- Target position for stabilization can be freely
selected
- Submicrometer resolution
Applications for beam stabilization
1. When using the Compact beam stabilization, the PSD detectors can be positioned before the laser is finally adjusted.
Once the laser has been adjusted, the target positions can be read out and the beam can be stabilized to these positions using the Set&Hold function.
2. The laser beam can be moved to different points with high precision by changing the target position on the detector.
In doing so, the laser beam follows the external target but remains stabilized at the highest resolution.
