Introduction
We at KingPo have dedicated more than 15 years to the development and refinement of laser test equipment that meets the stringent requirements of IEC 60825-1-2-12. In high-precision industries such as automotive, electronics, medical devices, and aerospace, even minor deviations in laser beam parameters can lead to defective products, safety incidents, or failed certifications. Our laser testing equipment delivers comprehensive, traceable data for beam profiling, power measurement, energy quantification, and spectral analysis, ensuring both performance optimization and regulatory compliance. This guide consolidates our practical expertise and technical specifications to assist engineers and quality managers in making informed decisions.
Why Laser Test Equipment Is Indispensable in Contemporary Manufacturing？
- Laser systems now operate at power levels ranging from milliwatts to kilowatts and pulse durations from femtoseconds to continuous wave. Without precise laser test equipment, manufacturers cannot reliably quantify critical parameters such as beam diameter, centroid position, ellipticity, power density, or temporal stability.
- Consequences of inadequate measurement include: • Increased scrap rates due to inconsistent cutting or marking quality • Safety risks from unverified beam divergence or energy output • Prolonged certification cycles and potential regulatory non-compliance • Reduced competitiveness in global markets that demand documented IEC 60825 conformity
- Professional laser testing equipment mitigates these risks by providing real-time, high-speed data acquisition (up to 10 000 Hz) and automated reporting, directly contributing to higher yield, faster time-to-market, and enhanced product reliability.
Understanding Laser Test Equipment Standards and Core Measurement Principles
The international benchmark is IEC 60825-1-2-12, which specifies safety requirements and standardized test methods for laser products. Our laser testing equipment is engineered to exceed every clause of this standard, supporting both continuous-wave and pulsed lasers across UV, visible, and IR wavelengths.
Key measurement domains include:
- Radiometric power and energy — using True RMS detection for accurate average and peak values
- Beam spatial characteristics — 2D/3D profiling with pixel-level resolution
- Temporal dynamics — high-frequency sampling to detect jitter and instability
- Spectral properties — wavelength accuracy to 1.9 nm resolution
Comprehensive Component Comparison Table
| Component | Model / Specification | Wavelength Range | Key Technical Index | Primary Application |
|---|---|---|---|---|
| Power Meter | Centuari True RMS + PD300 series | 200–1800 nm | 10 000 Hz recording, dual power/energy | Real-time stability & density calculation |
| Beam Profiler | BGS-USB3-SP932U | 350–1100 nm | 2048×1536 pixels, 3.45 μm pixel size | 2D/3D profile, centroid, ellipticity |
| Energy Probes | PE10-C / PE25-C | 0.15–12 μm | 25 kHz / 10 kHz max, high damage threshold | Pulsed energy measurement |
| Integrating Sphere | IS6-D-VIS-V1 | 0.4–1.1 μm | ±60° divergence, 20 μW–30 W | Total power for divergent beams |
| Miniature Spectrometer | SGM2020-VNIR | 350–1020 nm | 1.9 nm resolution | Spectral characterization of sources |
These components form a fully integrated laser testing equipment platform capable of handling large divergence angles and high LIDT (laser-induced damage threshold) requirements.
Key Features to Look for in Professional Laser Testing Equipment
When selecting laser test equipment, engineers should evaluate:
- Data acquisition speed ≥10 000 Hz to capture transient events
- Pixel resolution and dynamic range sufficient for micron-level beam analysis
- Motorized stages with sub-micron repeatability for automated alignment
- Comprehensive software with baseline normalization, fill factor, and automatic report generation
- Full traceability through ISO 17025-accredited calibration
Our systems incorporate all these features as standard, with modular design allowing future upgrades without hardware replacement.
Step-by-Step Operational Procedure for Laser Test Equipment
Step 1 – Installation and Safety Commissioning
Mount the laser source on the motorized linear/rotary stage. Connect the Centuari power meter, beam profiler, and safety interlocks. Verify compliance with IEC 60825-1-2-12 Class 1–4 requirements before powering on.
Step 2 – Beam Alignment and Profiling
Activate the BGS-USB3-SP932U profiler. Capture live 2D/3D intensity maps and adjust motorized stages until the centroid is centered within specified tolerance and ellipticity meets application requirements.
Step 3 – Power and Energy Characterization
Switch the Centuari module to power mode for continuous-wave measurement or engage PE10-C/PE25-C probes for pulsed operation. Record at maximum sampling rate to quantify stability, peak power, and energy density.
Step 4 – Spectral and Temporal Analysis
Insert the SGM2020-VNIR spectrometer for wavelength verification. Use the fast photodetector probe (FPS-1) when sub-nanosecond rise times are required.
Step 5 – Data Analysis, Reporting, and Archiving
The integrated software performs automatic calculations of beam diameter, power density, fill factor, and baseline normalization, generating fully traceable PDF reports compliant with IEC 60825-1-2-12 documentation standards.
