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.
Display: 5 1/2 digit LED Metric or Imperial Accuracy: 10 nm over the whole range Range: 4 mm Working Distance: 10 mm Probe: 5mm diameter 20 mm long
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.
