Multifunctional optical quality detector

The testing device includes standard collimator, scan type Hartmann diaphragm, focusing mirror, and CCD camera. The Hartmann diaphragm is installed on diaphragm bracket. Encoder is fixed on upper part of the bracket, and step motor and computer are installed on lower part of the bracket. Under control of computer, step motor drives scan type Hartmann diaphragm to rotate around optical axis, and computer receives image output from CCD camera and position information of scan type Hartmann diaphragm from encoder, and carries out data process for image. The invention can be applied for guiding fabricating optical elements, adjustment of optical path, evaluating qualities of incident beam and focal spot, possessing advantages of high testing precision, quick speed, and multiple functions.
