AutoNex Technologies develops practical engineering tools that help R&D and QC teams make better decisions earlier in their workflow. Our focus is on reducing wasted effort, cost, and uncertainty in thin-film research and device fabrication.
In many research labs, thin films that appear acceptable are taken forward to advanced characterisation (SEM, XRD, TRMC, profilometry, etc.) and device fabrication. Only after significant time and cost have been invested, the hidden defects become apparent — often through device failure.This frequently leads to:
Lost days or weeks of work
Expensive downstream testing on poor-quality samples
Subjective judgement calls instead of objective screening
Difficulty identifying and explaining yield loss
AutoNex tools are designed to identify issues early, before time-consuming and expensive downstream processes are applied.
OptiGate is an early-stage optical screening system designed to assess thin-film quality after deposition and annealing, before further processing.It provides rapid, objective insight into film quality while remaining fully non-destructive and process-agnostic.

What does OptiGate Detect?
OptiGate screens thin films for early-stage defect risks, including:
Non-uniform thickness and coating consistency
Surface and through-thickness cracks
Pinholes and hidden shunt pathways
Mechanical damage and continuity issues
Where OptiGate Fits in the Thin-Film Workflow
Synthesis → Deposition → Annealing → OptiGate Screening → Device Fabrication → Electrical Testing
At the bare film stage:
Meaningful electrical measurements are not yet possible
Device-level failures are expensive and late
Advanced characterisation is powerful but costly
A single rejected poor-quality film can save hundreds to thousands of dollars in downstream effort and prevent days to weeks of delay associated with booking and queueing for advanced characterisation tools such as SEM, TRMC, and XRD.OptiGate does not replace these expensive top-tier tools — it ensures their effective utilization.
Example Images of thin-film captured by OptiGate
Multiple images of the same film are presented below, with each image highlighting different defect features.



OptiGate V2 (In Development)
Planned extensions of the current optical screening platform include:
Wavelength-selective illumination for enhanced contrast and defect sensitivity
Spatial photoluminescence (PL) mapping for early material-quality insight
Early electronic-quality indicators derived from optical signatures
Further reduction in reliance on routine film-level advanced characterisation
OptiGate V3 (Exploratory)
Longer-term directions under exploration include:
Automated metrics
Data-driven acceptance thresholds
Integration with laboratory workflows
OptiGate is designed for teams working on:
Thin-film research and development
Perovskite and photovoltaic materials
Academic and national research facilities
R&D teams seeking improved yield, repeatability, and resource efficiency
