Overview
Sophisticated Analog and Digital beam positioning system.
The system offers real time measurement of laser displacements with update rate of up to 30 KHz (for the 9x9mm PSD) and up to 60 KHz (for the 4x4mm PSD) and resolution of 1 um. Special high resolution versions with limited dynamic range are offered: up to +/- 0.1 um for the 4x4mm and up to +/- 0.2um for the 9x9mm PSD.
The system measures both CW and pulsed beams, and offers an external trigger for synchronized data acquisition.
Multiple devices control via USB port is available (up to 8 devices).
