查询词典 narrow-band

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。
