HP 10886A PC Compensation Board


 [ Summary ][ Features ][ Specifications ][ Ordering ][ Assistance ]

Product Summary

The HP 10886A PC Compensation Board increases the accuracy and repeatability of HP's PC-based laser interferometer positioning systems. Using HP 10751C/D environmental sensors, the HP 10886A detects and compensates for changes in the system's operating environment. Resulting errors can be compensated to provide a system accuracy up to +/- 1.5 ppm. The HP 10886A also compensates for thermal expansion errors detected by HP 10757D/E/F Material Temperature Sensors.

As part of an HP PC-based positioning system, the HP 10886A can be used to improve performance in high-density disk drive applications (servo-track writing), and IC inspection and repair (X-Y stage positioning). The exceptional accuracy of the laser system allows the precise positioning and motion control required for the consistent manufacture of high-quality products.

Product Features

Environmental Compensation

Each measurement depends on the wavelength of light (WOL) as its basic scale length. Changes in air temperature, pressure, and humidity change the air's index of refraction, which in turn changes the WOL in air. The HP 10886A uses the HP 10751C/D Air Sensor to measure and compensate for the changes.

Thermal Expansion

Measurement errors can result from thermal expansion of the workpiece or machine being measured. Up to three HP 10757D/E/F Material Temperature Sensors can be used with the HP 10886A to measure material temperature and to compensate for thermal expansion.
