Camera Image Size
defines the active area of the camera used for measuring
the wavefront. This setting should be adapted to the beam size applied to the
instrument. Limiting the used camera size will reduce the unused sensor area and
increases measurement speed because of saving time for evaluating the spotfield
images.
The following area sizes can be selected:
The camera offers a maximum of 1280 x 1024 pixel = 1.3 MegaPixel on a
rectangular area 5.95 x 4.76 mm. For beams that have a larger diameter than
4.76 mm, only a fraction of the beam cross section can be analyzed by the
instrument. The Wavefront Sensor is 'over filled' regarding the entrance aperture
but can still yield correct results. In this case special care must be taken to the
pupil parameters (see
).
The following graph illustrates the selectable image sizes.
