HP 5526A Laser Interferometer Page



My system.  Click to enlargeLaser tripodThe basic HP 5526A and the original model HP 5525 Laser measurement systems are comprised of a laser head and display plus optics for various different types of measurements. For a basic system description please read the  Operator's Handbook.  Automation accessories were based on the HP 9825 calculator.  A program package for laser metrology using the HP5526A/9825A/9872A combination was provided with the calculator option (see below).  Several Application Notes were published to support laser metrology, including 156-2, "Calibration of a Surface Plate", and 156-5, "Measurement of Straightness of Travel".  These are the only two that I have.  I would like very much to obtain the others, particularly one titled "Calibration of a Machine Tool" (if memory serves).  I also would like to obtain original service manuals for the 5505A display/5500C laser head and 5510 Automatic Compensator.    Another accessory I need is the remote control box, which contains a reset button, alignment meter and print button, connected to the 5505A display by a long cable.   I received a request for the Compensation Factor Handbook, which I scanned into a 6 MB pdf format (available on request).  I also have written a small spreadsheet using the formulae given in the handbook to calculate the compensation thumbwheel setting.  Click here for available documentation.
