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.
SpotOn USB 2.0-Position Sensing
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.
