In spectral analysis, photoelectric detection, weak signal measurement, and automated experimental scenarios, the data collector serves as the core bridge connecting photovoltaic devices with the analysis system. Beijing Saifan Optoelectronic Instrument Co., Ltd. has launched the 7IDA1/7IDA3 series data collectors, featuring four core strengths: nanometer-level weak signal capture, dual-channel synchronous precise acquisition, millisecond-level high-speed sampling, and intelligent adaptation for all scenarios. Each weak light signal can be reliably captured and accurately converted, making them the "precise data hub" for scientific research and industrial detection, redefining the efficiency and accuracy standards of optical signal acquisition.
1. Nanometer-level perception, no "disappearance" of weak signals
The Saifan data collector is equipped with ±15Bits/16Bits high-precision A/D converters and low-noise operational amplifiers, with a full dynamic range, easily breaking through the signal acquisition upper limit of traditional equipment. It has dual-channel fully symmetrical input channels, which can flexibly switch between DC voltage / DC current modes. Voltage measurement covers ±0.5μV to ±4V, and current measurement is as low as ±5pA to ±40μA, accurately capturing nanometer-level weak optical currents and microvolt-level weak voltages, perfectly adapting to scenarios such as fluorescence microscopy, photodiode response, and weak signal detection of photovoltaic materials. It also features a 1–256 programmable gain adjustment button, allowing for quick adaptation to both strong and weak signal scenarios without the need for additional external amplifiers, significantly simplifying system setup and reducing integration costs, making research and production line debugging more efficient.
2. Dual-channel synchronization + precise triggering, zero error in multi-device collaboration
As the "time commander" of the optical system, the Saifan data collector has built-in trigger input/output channels, which can be seamlessly synchronized with monochromators, spectrometers, filter wheels, and motion platforms, achieving perfect alignment of wavelength scanning, light modulation, and data acquisition timing, completely solving the timing error problem in multi-device collaboration. It has dual-channel 12Bits D/A output channels (0–10V/-10V to 10V), which can directly control light source power, filter wheel switching, and stage movement, supporting closed-loop automated experiments, making continuous measurement without human intervention a reality. It also supports single-channel measurement and ratio measurement, allowing for simultaneous acquisition of reference signals and measured signals, automatically calculating ratios, effectively eliminating errors caused by light source fluctuations and environmental interference, with data reliability improved by 60%.
3. High-speed sampling + full protocol compatibility, plug-and-play without barriers
The 7IDA3 is equipped with a high-speed USB2.0 interface, with a sampling rate of up to 100KHz, meeting the real-time acquisition requirements for rapid spectral scanning and dynamic light intensity changes monitoring; the 7IDA1 is equipped with a standard RS232 serial interface and a parallel interface specifically for 7ISW series spectrometers, suitable for traditional optical system layouts. The complete software ecosystem provides 7IDA1U.ocx control and dedicated software 7IMSS, 7ISWS, fully supporting secondary development in LabVIEW, VB, VC environments, allowing users to quickly build custom test systems without having to write low-level drivers from scratch, significantly shortening the development cycle and lowering technical barriers. The entire machine is lightweight, with the 7IDA3 weighing only 1.35kg, easy to install, suitable for desktop experiments, portable detection, and industrial production lines, etc.
