Scale limitation: best suited for large fabs, not smaller manufacturers
Camtek has long been a fixture in semiconductor inspection, with systems like Eagle, Falcon, and Gryphon widely used in fabs.
Its Automatic Defect Classification (ADC) software is dependable for catching common, repeatable defects through template matching, and users often highlight the strong support and training that comes with it.
Where it falls short is in adaptability. Unlike AI-native platforms, Camtek requires manual calibration and updates, making it less effective against unknown or complex defect types. Reviewers note higher false reject rates and slower responsiveness to new challenges.
For fabs with stable, well-understood defect profiles, though, Camtek remains a reliable option.
Features
Image-based automatic defect classification (ADC)
Built-in setup tools for re-training and qualification
Flexible classification engine for standardized data
Strong support and training ecosystem
Pros:
Reliable for consistent, known defect types: Performs well with familiar defect patterns

How To Choose?
Choosing the right system comes down to more than just accuracy claims. You’ll want to weigh how well the software aligns with your production environment, industry, and long-term goals.
Here are the key criteria – and how the five options stack up:
1. Accuracy and Precision Requirements
If your process demands submicron or nanometer-level defect detection, accuracy is non-negotiable. Semiconductor fabs and advanced electronics lines fall squarely in this category.
Stronger options: Averroes.ai (99%+ accuracy with continuous learning) and KLA (high precision at ≤5nm nodes).
Less strong: Camtek, which works reliably for known defect types but struggles with complex or unknown anomalies.
2. Ability to Detect Unknown Defects
Many systems can flag known, repeatable defects. But in dynamic environments, you need software that can adapt.
Stronger options: Averroes.ai stands out here with unsupervised learning that captures both known and unknown defects.
Less strong: Camtek (template matching only) and Mirtec (excellent speed and imaging, but relies on predefined profiles).
3. Ease of Deployment and Setup
Complex inspection shouldn’t require months of onboarding or a team of specialists.
Stronger options: Averroes.ai (no-code deployment) and Cognex (EasyBuilder step-by-step setup).
Less strong: KLA and Mirtec, which require skilled setup and are more suited to large fabs with dedicated engineering support.
4. Hardware vs. Software Flexibility
Decide if you want a turnkey solution (hardware + software) or software that layers onto your existing equipment.
Software-first flexibility: Averroes.ai integrates with existing cameras and infrastructure, minimizing capital spend.
Hardware-bound systems: Cognex, Mirtec, KLA, and Camtek all package hardware with their software, which can increase cost but may appeal to buyers wanting a single-vendor solution.
5. Speed and Throughput
Production speed matters – inspection software should keep pace without bottlenecks.
High-speed leaders: Mirtec (sub-second inspection with turbo mode) and KLA (fab-level throughput).
Balanced: Averroes.ai, which delivers scalable software speed without large machine footprints.
Less strong: Camtek, where frequent calibration can slow operations.
6. Industry Versatility
Some systems are narrowly designed, while others can adapt across sectors.
Most versatile: Averroes.ai, proven in semiconductors, electronics, pharma, food & beverage, solar, and even oil & gas with drone inspection.
Broader but still niche: Cognex (good for electronics, packaging, automotive) and Mirtec (electronics-focused).
Narrowest: KLA and Camtek, largely limited to semiconductors and PCB manufacturing.
7. Cost and ROI
Upfront cost and long-term return both matter. A system that saves labor hours or boosts yield often pays for itself quickly.
Cost-efficient with high ROI: Averroes.ai (software-only, saves 300+ labor hours per application monthly).
Higher cost but justified in fabs: KLA and Mirtec.
Expensive relative to flexibility: Camtek, especially given its limited adaptability.

Frequently Asked Questions
What’s the difference between machine vision software and hardware-based inspection systems?
Machine vision software focuses on algorithms and AI models that analyze images, while hardware-based systems bundle in cameras, lighting, and processors. Software-only solutions integrate with existing equipment, whereas hardware bundles may increase cost but simplify vendor management.
Can machine vision software integrate with legacy production lines?
Yes, many platforms (like Averroes.ai) are designed to work with existing cameras and automation infrastructure. Others may require proprietary hardware or upgrades, so compatibility should be confirmed before purchase.
How much training data is needed to build an accurate defect detection model?
This varies widely. Traditional systems may need thousands of images, while AI-driven platforms can start with as few as 20–40 images per defect class and improve continuously over time.
Does machine vision software require constant recalibration?
Not always. AI-powered systems with continuous learning adapt automatically to new defect patterns, reducing the need for recalibration. Older or template-based platforms often require more frequent manual adjustments.
Conclusion
Finding the best machine vision software for defect detection comes down to matching the tool with your production needs.
Some platforms, like Cognex, stand out for flexible rule-based and AI inspection. Mirtec is a strong pick for high-speed 3D AOI in electronics, while KLA remains the heavyweight for advanced node wafer inspection in large fabs. Camtek fits manufacturers with established, repetitive defect profiles.
Averroes, though, combines adaptability, accuracy, and scalability – catching both known and unknown defects across industries from semiconductors to pharma, food and beverage, and solar.
