Selection Considerations

When choosing an optical power meter, consider:

• Sensor Type: Photodiode sensors (Si, Ge, InGaAs) are fast and sensitive but wavelength-dependent; thermopile sensors handle higher powers and broader wavelengths .
• Wavelength Range: Ensure the meter covers the wavelengths used in your fiber-optic network or laser system.
• Portability vs. Durability: Handheld meters are convenient for fieldwork, while benchtop models offer higher precision for lab use.
• Integration: Some meters combine visual fault locators, cable testers, or data logging for efficiency.
• Calibration and Accuracy: Check calibration intervals and measurement uncertainty, especially for critical applications.
