Professional to provide a full range of foreign four-quadrant detector (PIN four-quadrant, InGaAs quadrant and APD quadrant detector), a different area of ??light, built-in amplifier and resolution optional, high-response (dynamic range), reliability good, wide temperature range. Response wavelength ultraviolet light, visible light (sunlight, natural light), 650nm laser, infrared light, of YAG 1064nm and 1310nm, 1550nm, etc., and with a processing circuit board (integrated anti-aggravation of the nonlinear error is small, accuracy of GAP optional direct output X, Y position signal). To provide comprehensive technical support, a variety of different packages, excellent cost-effective, long-term stock, the typical model QP1-6, QP2-6, QP10-6, QP20-6, QP50-6, QP100-6, we also provide high-precision four-quadrant system can be connected directly to the computer with the display software can live demonstration of the track location and the location coordinates of the laser spot and the measurement process, please contact us. 
 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
