Simultaneous measurements of position and angular displacements.
The system offers real time measurements of beam position and angular displacements as well as power display, with resolution down to 0. 1 um.
The system measures CW beams, and offers portable, fast and accurate beam alignment solution.
It is a USB2.0 device, the system runs on any Notebook computer with Windows 7 OS (32 & 64 bit).
Multiple devices control via USB port is possible. Data streaming via TCP/IP communication protocol or RS232.
ActiveX software for integration in customer’s application program is available. A complete system based on a sensor head with 3m long attached cable, an electronics box with USB2.0 cable, software on CD disk, carrying case.
