Each of the 200 shapes is numbered so that comparison can be done with particles in the specimen, and the details logged and communicated. Is also a useful tool for calibration and operator training. The particle sizes range from 1197um² to 42308um². A Type Test Report that gives size and area information of all 200 particle shapes can be supplied - example pages from this report are shown in the images.

Graticules Optics have facilities to manufacture random and regular patterns for the calibration of particle sizing and counting systems. Typically these may comprise regular shaped features of different sizes so that the imaging software has known reference sizes to set it's calibration. Alternatively, they may have a field area populated with 'random' shaped and sized features. Contact us with your requirements.
