Measure the radiant power in milliwatts per square centimeter. Uniformity across the illuminated area should not vary by more than 10 percent. Uneven SWIR Vision Light causes calibration drift in line-scan systems.
2.3 Thermal Management Capability
SWIR LEDs generate significant heat. Quality designs incorporate aluminum substrates, thermal vias, or active cooling. Without proper heat dissipation, the SWIR lighting system will experience rapid degradation and wavelength shift.
2.4 Lifetime and Lumen Maintenance
Reputable manufacturers provide L70 or L80 lifetime data at rated current. A good SWIR illumination module should maintain at least 70 percent of initial output for 50,000 hours under standard conditions.
2.5 Optical Design Flexibility
Check for available beam angles, diffuser options, and custom lens configurations. Standard SWIR Light Source options include 10°, 30°, 60°, and 120° beam spreads. OEM manufacturing partners often offer custom optical designs for specialized applications.
2.6 Electrical Compatibility
Verify input voltage range, drive current requirements, and strobe capability. Many industrial systems require 24V DC input with pulse-width modulation support. A quality global supplier provides detailed electrical specifications in the datasheet.
2.7 Environmental Protection Rating
For factory floor installations, IP54 or higher is recommended. Outdoor or washdown applications may require IP67-rated housings. Always confirm the operating temperature range, especially for high-heat environments.
| Criterion | Food Inspection | Semiconductor | Recycling |
|---|---|---|---|
| Wavelength (nm) | 1200 - 1700 | 1450 - 1550 | 1000 - 1300 |
| Power Requirement | Moderate | High | Medium |
| Uniformity Tolerance | +/- 8% | +/- 5% | +/- 12% |
| Thermal Management | Passive | Active | Passive |
| IP Rating | IP54 | IP54 | IP65 |
