How does the precalibration at 514nm, 532nm, 632.8nm, and 650nm affect measurement accuracy across the full 400–1100nm range of the Atomfair-OPM-628?
The Atomfair-OPM-628 is precalibrated at 514nm, 532nm, 632.8nm, and 650nm to compensate for the nonlinear wavelength response of the PIN photodiode, ensuring optimal accuracy at these four specific wavelengths. For other wavelengths within the 400–1100nm range, the specified measurement uncertainty is ±3% ±1 digit, with best performance achieved when the measured wavelength closely matches a calibrated line. The instrument's sensitivity of 0.1μW and resolution of 0.1μW apply across the entire range.
Can the Atomfair-OPM-628 be integrated into an automated data acquisition system?
Yes, the optical power meter supports communication with an upper computer via both serial port and USB interfaces, enabling seamless transmission and subsequent processing of measurement data. This connectivity also allows for custom application development, making it suitable for automated test benches and remote monitoring in laboratory or production environments.
What are the power supply requirements for the Atomfair-OPM-628, and can it be used with 110V mains?
The Atomfair-OPM-628 requires a 220V AC power supply at 50–60Hz. It does not feature automatic voltage switching, so for use in regions with 110V mains, a step-down transformer rated for at least the instrument's consumption must be employed. The unit's display is a 3-1/2 digit readout.
The Atomfair-OPM-628 Optical Power Meter provides calibrated optical power detection from 0.1 μW to 200 mW across 400–1100 nm using a 10 mm × 10 mm PIN photodiode, with factory calibration at 514, 532, 632.8, and 650 nm to compensate for wavelength-dependent detector response. Its serial and USB interfaces support data acquisition and custom application development, though the 220 V AC power requirement and ±3% ±1 digit uncertainty impose operational constraints for field or high-precision metrology use.
Positive
- High-sensitivity PIN photodiode: The 10 mm × 10 mm PIN photodiode achieves 0.1 μW resolution and a 0.1 μW–200 mW measurement range, enabling detection of low-level optical signals across the 400–1100 nm spectral band.
- Multi-wavelength calibration outputs: Factory calibration at 514, 532, 632.8, and 650 nm compensates for the detector's nonlinear spectral response, improving measurement accuracy when using common laser and LED sources.
- Serial and USB data interfaces: The serial port and USB connectivity allow seamless transfer of measurement data to upper computers and support custom application development for automated test and data logging workflows.
Trade-offs
- Mains power dependency: The instrument requires a 220 V, 50–60 Hz AC supply, which limits portability and may necessitate a power inverter or transformer in field or battery-powered applications.
- Calibration-limited accuracy: Measurement uncertainty is ±3% ±1 digit, and accuracy is only guaranteed at the four factory-calibrated wavelengths; measurements at other wavelengths within the 400–1100 nm range may exhibit additional error due to the detector's nonlinear response.
