Optical measurement of mesh sizes with the compact 'Profile Projector'.


In contrast to mechanical testing methods with test sand or glass balls, optical measurement of mesh dimensions is a fast and reliable measuring method and ideal for inline control of manufacturing results in an Industry 4.0 environment.

The evaluation of the mesh size distribution and the traceability to corresponding standards, such as ASTM E 11, can be realized with Opto's new Imaging Module Profile.

The profile projector comes pre-calibrated from the factory. Opto offers calibration standards with and without DKD certificate to recalibrate the optics regularly.

The profile projector works with a telecentric brightfield illumination and a tuned telecentric objective in transmitted light mode.
