What is the measurement accuracy of the LPA-825's power meter for low-power laser beams near 0.1 mW?
The power measurement accuracy is ±0.5% over the full range of 0.1 mW to 20 W, complying with international laser power meter calibration specifications. This accuracy is maintained across the entire dynamic range, including low-power measurements, ensuring reliable data for teaching and research applications.
Can the LPA-825 system measure both beam quality (M² factor) and pulse parameters for pulsed lasers?
Yes, the system includes a pulse parameter tester for measuring pulse width, repetition frequency, and peak power, and a beam profiler that measures the M² factor following ISO 11146 international standard with a measurement error ≤0.05. The modular design supports combined measurement of pulse and beam parameters for pulsed lasers within the compatible wavelength range (e.g., 532 nm, 1064 nm, 1550 nm).
What safety certifications and environmental conditions are required for operating the LPA-825 system?
The LPA-825 complies with Class 1M international laser safety specifications and IEC 61010 teaching equipment safety standards. It operates reliably at 10–35 °C with relative humidity ≤75%, meeting international environmental standards for laboratory educational equipment.
The LPA-825 integrates power, wavelength, polarization, and M² beam quality measurement into a single modular platform, with accuracy specs (power ±0.5%, wavelength ±0.1 nm, M² error ≤0.05) that meet teaching-grade international standards. Its multi-wavelength source compatibility (632.8/532/1064/1550 nm) and ISO 11146-based beam profiling make it a practical benchtop system for undergraduate and postgraduate laser metrology labs, though its 10–35°C operating range and Class 1M laser safety classification impose environmental and handling constraints.
Positive
- Multi-parameter laser metrology integration: Combines power/energy, wavelength/spectrum, polarization, and M² beam quality measurement in one modular host, enabling comprehensive laser characterization without multiple standalone instruments.
- Teaching-grade accuracy with ISO compliance: Power accuracy ±0.5%, wavelength accuracy ±0.1 nm, and M² error ≤0.05 align with international teaching standards, while beam quality measurement follows ISO 11146, ensuring reproducible and defensible data for academic labs.
Trade-offs
- Narrow environmental operating envelope: Rated for 10–35°C and ≤75% relative humidity, the system requires climate-controlled lab conditions; exceeding these limits can degrade measurement stability and accuracy.
- Class 1M laser safety handling requirements: Class 1M classification means the laser output can be hazardous if viewed with optical instruments; users must implement appropriate beam containment and eye-safety protocols during alignment and measurement.
