Multisensor Measuring Machine

August 1, 2011

The O-Inspect multisensor measuring machine from Carl Zeiss allows the inspection of complex parts. A chromatic white light sensor is now available for this machine.

The white light sensor enables the measurement of parts that cannot be captured with a contact sensor or a camera. This includes very small and sensitive workpieces that have a transparent, glossy, or low-contrast surface. Reflections or lack of contrast, which can impede the correct focusing of a camera, is no longer a relevant factor. With the addition of a chromatic white light sensor to this machine, even workpieces such as these can be measured with maximum precision, the company states.

The workpiece is illuminated with bundled white light. Special optics with chromatic aberrations in the probe split the light into its spectral colors. A spectrometer analyzes the reflected light and determines which color has the highest intensity. The measuring machine can determine the distance from the sensor to the surface using the spectral color – and derives the exact topography of the part from this information.

The results are displayed using the company’s CAD-based Calypso measuring software. It enables size, form, and position measurements with systematic user guidance and makes deviations visible and quantifiable.

Furthermore, this machine has an additional light source on the contact scanning sensor that can be turned on to illuminate the measuring field when the machine is reprogrammed.
