Iris™ Optical QC

Iris™ Optical QC

Arrayjet has developed a dual-camera optical QC system, available now on the Marathon series of microarray printers.

The Iris™ 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.

Optical QC System

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.

Customisable thresholds

Users have the option to select a threshold for the 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

Arrayjet AJI Viewer

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.

Defect Highlighter

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.
