| Abstract: | An improved device and testing system for the precision test of a germanium wedge, which have unique characters, are constructed. Using micro displacement mechanisms and divided drive manner under the control of a computer by means of search skills, the test work is done with great facility. The analysis of errors is presented in detail. It is proved to be efficient and practical that the system can meet the test requirements after finishing the tests on well calibrated standard germanium wedge. The system and attached device can also be available for other uses, such as optical components and graduation of angles. |
| Keywords: | wedge micro displacement mechanisms measurement |
