The target can be any surface giving specular reflection to the probe, and can be integrated with the probe head to form transducers which measure changes in pressure, temperature, or refractive index. The target may be scanned by the probe to measure surface profiles with micron spatial resolution.

|115/220V AC, 1 Amp
|17.75" x 11.75" x 5.25"
Operation: +10 to +35 deg C Storage: -20 tp +50degC
|1cm working distance, 10 micron spot size, standard, Focla Depth +/-2mm
|Digital; to DAQ card of PC compatible witjh NI 6533 series for PCI

The PD-1000 offers an accuracy of up to 1 nm over several millimeters range of displacement. The measurement is truly linear and based on an interferometric phase comparison that is independent of light level.
|5 1/2 digit LED Metric or Imperial
|10nm over the whole range
|5mm diameter 20mm length
An embedded microcontroller performs all the data acquisition and processing functions and outputs the data to the remote display.
LED's on the controller front panel indicate system status.
Zero may be set at any position within the range by operation of a remote control push button. Measurements are relative to this zero position.
This configuration is used with a nominally reflective target perpendicular to the probe axis.
