Pyser-SGI 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.
The SG7 Test Slide detailed below is a unique product with random shaped and sized features that can be used for training and calibration purposes. A 'type test' report is now available giving size and area information for each feature.
