The feedback resistance, R1, is dependent on cell sensitivity and should be chosen for either maximum dynamic range or for a desired scale factor. R2 is elective: in the case of photovoltaic cells or of photodiodes, it is not required in the case of photoconductive cells, it should be chosen to minimize bias current error over the operating range.

反馈电阻R1的取值由电池的灵敏度和要求的最大动态范围，或者需要的电流——电压转换比例决定。R2分情况选取：在光电池和光电二极管时不需要这个电阻，在光电导的时候，电阻的阻值应该能使在工作范围内，由OP输入偏置电流所带来的误差最小。

Choose the 890nm infrared LED as the light source after compared the capabilities of incandescent lamp/tungstic lamp and LED/LD and also think about the selective absorbability of water; it has strong points such as constant light intensity,long life, narrow light spectrum,etc, and use the infrared light with 890nm wavelength to decrease the influence of optical-absorption matters.Choose the photosensitive diode which suitable to the LED which we choosed after compare the capabilities of light sensitive resistor, photocell, photosensitive diode and phototriode. Both of these make up the photoelectric system of turbidimeter.

通过比较白炽灯／钨灯和发光二极管／激光二极管的各项性能指标，考虑到水对光线具有选择性吸收作用，选择890nm的红外发光二极管作为浊度仪的发光器件，其有发光光强稳定、寿命长、发光光谱窄等优点，且用波长大于800nm的红外光进行测量可以大大减小水中光吸收物质的影响；通过对光敏电阻、光电池、光敏二极管和光敏三极管等光敏器件的各项性能的分析与比较，选择响应时间短、输出特性线性度好的光敏二极管作为光接收器件，并与红外发光二极管相配套，构成浊度仪工作的重要系统——光电系统。
