Description
Technical field
This utility model relates to field of optical device technology, particularly relates to a kind of optical wave plate testboard.
Background technology
Light wave has different polarization states, optical system it is frequently necessary to change the polarization state of light wave or the polarization state of detection light wave, owing to the polarization state of light wave is to be determined with phase contrast by the amplitude ratio of its orthogonal vibration, therefore changing the two parameter and just can change the polarization state of light wave, the class optics utilizing light to be made by the feature of the phase contrast of crystal change incident illumination is known as wave plate.
During optical wave plate part processing and manufacturing, needing grinding repeatedly, polishing, wave plate part needs to detect according to its performance parameter, it is ensured that the wave plate part of processing meets the requirements.During detection wave plate part, need constantly to adjust the polarizer, position, plane included angle between wave plate part to be detected and analyzer, periodically changed by the intensity of the light of analyzer and detect, prior art needs to use in detection the most constantly goes to adjust, use adjustment test and comparison manually slow, it is relatively difficult to quickly adjust test, it is therefore desirable to improve further.
