Iris™ Optical QC
Arrayjet has developed a dual-camera optical QC system, available now as an upgrade on the Marathon series of instruments.
The Iris™ system consists of twin cameras mounted on either side of the print head. Each camera captures images within 300 ms of sample deposition, moving across the printed slides in conjunction with the print head.
Images are processed in real time, detecting the presence of missing spots, artefacts, merged or misaligned features. Upon completion of the print run, print quality for each slide of the entire batch is reported. These images can be accessed immediately and also saved for future reference and traceability.
A final report will inform the user of the percentage of imperfections on a slide-by-slide basis.
Users have the option to select a threshold for quality of the printing. Percentage of missing spots and/or other defects can be chosen from the setup window before the printing starts.
Positional accuracy and spot diameter variations can also be reported, if requested.
Imaging and reporting of defects
The print quality report of each individual slide includes images of the printed spots captured in real time. The Command Centre software analyses each image and generates qualitative and quantitative data for any detected defects.
A global report for the quality of the whole manufacturing run is generated automatically and can be saved to ensure complete traceability of manufacturing runs.
The software highlights to the user the defects found and categorises the defect type such as missing spot, artefact, merging spots, satellites present or misalignment.
Integration of the Iris™ with Arrayjet Marathon instruments gives access to a reliable QC system for reliable high-throughput batch manufacturing.
