High-Intensity LED UV Inspection for Flawless Defect Detection

How to Choose the Right LED UV Inspection System

1. Determine Your Application

• Molding/Shaping/Drilling/Turning Processes – Inspection and verification of produced parts for flaws

• Non-Destructive Testing – magnetic particle inspection (MPI), fluorescent penetrant inspection (FPI)

• Counterfeit detection for security features in documents or packaging

Assessing different applications will help achieve the appropriate intensity levels, beam dimensions, and safety standards for certification required.

2. Verify the UV Wavelength

• For inspections, 365 nm (UV-A) is most widely accepted.

• For the inspection of fluorescent materials, ensure the lamp produces minimal visible light to avoid interference.

3. Evaluate UV Irradiance and Geometric Coverage

• Inspections with high-intensity output (e.g., over 1,200 μW/cm² at 15 inches) are faster and more effective.

• If large surfaces must be assessed, look for systems with a broad uniform beam.

• A narrow focused beam is best for small areas and detailed inspections.

4. Look for Certification and Compliance

Confirm the system meets the following certifications (if applicable) to the business sector’s compliance:

• ASTM E3022

• ISO 3059

• Rolls-Royce RRES 90061 (if aerospace applicable)

These certifications assure dependability and eligibility for regulated environments.

5. Consider Portability Versus Stationary Use

• Handheld: Light-weight instruments are powered by batteries for mobility or field examinations.

• Stationary/bench-top: More powerful instruments better suited for laboratories or production environments.

6. Check for Capability of Dual Light Source

• Some systems equipped with UV LEDs and white light LEDs offer toggle capabilities for switchable modes during inspection and documentation.

7. Structural Performance and Environmental Adaptability

• Ensure enclosures with IP ratings (IP65 for instance) are protected from dust, water, and other rugged environments.

• Choose materials that are resistant to impacts when working in industrial or field settings.

8. Other Considerations

• Built-in cooling systems for extended use

• Light adjustability

• Battery life for portable models

• Ergonomics of contour, weight, and design

• Warranty terms and support for services after purchase
