AUTOCOLLIMATORS WITH CCD-CAMERA MOUNT
The principle, function and layout resemble the autocollimator with 90°-viewing (see page 46). The eyepiece and the eyepiece reticle are replaced by a mount for a CCD-camera and the autocollimation image is directly imaged on the camera chip when the camera is mounted. With no eyepiece reticle the displacement of the return image is measured on a video monitor or using a computer, frame grabber and software .
Application areas:
■ Measurement of angular tilt
■ Measurement of parallelism of plane plates
■ Adjustment of optical elements
■ Qualitative testing of the imaging properties of optical elements and systems
Notes on ordering:
■ One Reticle and 6V/5W illumination w/cord are included.
More notes on ordering:
■ CCD-camera and computer hardware/software are NOT included.
■ As this type of autocollimator does not have an eyepiece reticle a direct measurement of the reticle displacement is impossible. Additional computer with software and frame grabber is needed.
■ For angular measurement the autocollimator should be equipped with a negative crosshair reticle . For testing of imaging quality use resolution target or Siemens Star .
■ If not specified otherwise, the autocollimator is adjusted to infinity at 546 nm wavelength. Adjustment to other distances or wavelengths is also possible on demand.
■ The nomenclature of the autocollimators with CCD-camera mount is as follows:
Important: Please specify collimator reticle as well as illumination when ordering.
