Bilimit Illumination Digital Photometer

    摘要
  • 摘要: 双向照度数字测光仪由光敏元件(SPD等)、CMOS数字集成电路、语音集成电路、A/D转换器及LCD液晶显示器组成,对光照度进行声光及数字处理,在大照度范围(0～20000lx)连续测光及双向(强、弱)照度数字监控.

     

    Abstract: Bilimit illumination digital photometer is made up of Si photodiode(SPD), CMOS digital integrated circuit, language music integrated circuit, analog digital converter (A/D) and liquid crystal display(LCD). The photometer can measure light in digital processing. It can conform to the wide illumination range from zero to 20 000 lx and bilimit illumination digital measuring.
