The NPS2100 is a NanoSensor, high voltage amplifier and control electronics combined as a single channel standalone module, powered by an external +/-15V, 130V and -30V DC supplies.

The NPS2100 is a NanoSensor, high voltage amplifier and control electronics combined as a single channel standalone module, powered by an external ±15V, 130V and -30V DC supplies.

The controller can be used to provide closed loop position control of translators, X-Y stages, mirror steering mechanisms etc. Alternatively it can be used open loop as a piezo controller and NanoSensor.

The control electronics allows the user to optimise the NPS2100 closed loop response. Closed loop operation gives vast improvements in stability and linearity over open-loop operation.

Features

• Subnanometer position resolution
• Linearity error down to 0.02%
• User adjustable measurement bandwidth (50Hz, 500Hz or 5kHz)
• User adjustable amplifier gain (for applications that do not use the full measuring range)
• Selectable long ('-L') or short ('-S') measuring range (2pF or 10pF capacitance)

Applications

• Disk drive head testing
• Mask / wafer chuck alignment
• Scanning Probe Microscopy
• Optical cavity tuning
• Interferometry

Variants

• 2100 - Standard
• 2100-20 - Extended output range (lower limit reduced to -20V)
• 2101 - No NanoSensor screen driver
