This HP Laser Interferometer Positioning System was taken from a huge semiconductor chip inspection & alignment equipment (The whole equipment was sitting in an storage room for more than 10 year). It was used for the precise X and Y stage movement.  The system includes all the parts for the position measurement excepts two 1-foot-long mirrors on the stage: one HP 5517B Laser (403 uW); working;  2 HP 10706B interferometers;  2 HP 10780C interferometer receivers;  one HP 10701A beam splitter;  one HP 10707A beam bender;  one Anrad box that integrates a power supply for HP laser and a HP 10764-60005-T interferometer circuit board; lights on;  one HP laser power cable and X & Y axis cables connecting the receivers to 10764-60005-T. I am not familiar with this item  and thus don't know how to test it. The laser is working. The green "Ready" light flashes after the power is on and stay stable after a few minutes. The interferometer and the receiver for Y axis are leveled on a piece of metal. The ones for X axis were taken off from a heavy piece of metal in order to reduce the shipping cost. The receivers are in good cosmetic shape while the interferometers, the splitter and the bender have the rust stains in the surfaces but with excellent optical quality. One of the receiver cable has a black insulation tape on it indicating the cable was cut before.   Please carefully look at the pictures and let me know if you have further questions. I might ship it in two different boxes if I don't find a right-size box. Free local pick up!
