Overview

A portable, fast and accurate optical beam positioning system having a USB2.0 interface.

The system is based on a 24 bit A/D electronics box, powered via the  USB2.0 port.

It offers simultaneous operation of one or two PSD's in one system. 

The PSD's are Lateral Effect type or Four-Quadrant type.  There is a variety of sensor head types and sizes.

The update rate is up to 150 Hz when using a 500 Hz digital filter. The spectral range is 350-1100nm.

The application program is compatible with Windows 7/8/10 OS (32 & 64 bit). For custom integration, an SDK package software is offered as standard.

(*) To maintain full calibration accuracy, attenuating optical filters may be necessary for operation with beams greater than 1 mW. Saturating "non-linear" effects depend on the beam size, type and wavelength, but caution should be exercised when using the 4Qaud PSD above 3-6 mW or the Lateral Effect PSD above 1-3 mW
