The basic functions of the four-quadrant detector digital processing module is a four-quadrant detector, the light intensity signals are converted into digital signals, and through the USB interface to transfer data to a computer for display, analysis or storage, to meet the four-quadrant data processing requirements. The signal processing module has a high signal conversion accuracy and powerful data processing software. Another natural light-sensitive built-in four-quadrant detector amplifier circuit, four-quadrant detector, the UV-sensitive four-quadrant detector, and a wide temperature range four-quadrant detector series, four-quadrant detector application board, the typical model the: OSQ16-SD2 OSQ20-SD2, OSQ50-SD2, OSQ100-SD2. if necessary, please contact us at :021 -54,971,821
