The 71889 Amplified UV Silicon Photodetector for Optical Power Meters is operated in photovoltaic mode for best DC and low frequency performance. This calibrated 10 mm x 10 mm UV Silicon detector has a 185 to 1100 nm range, which enables spectroradiometric measurements to be made. This version has a built-in trans impedance amplifier. The amplifier provides trans impedance gains from 10^4 V/A to 10^9 V/A. It also offers three selectable time constant settings in order to match the upper bandwidth limit of most experimental needs. The lowest noise levels can be achieved by operating at the lowest bandwidth setting. This amplified model requires +/-15 V DC to operate, which the Laboratory Power Supply models 70703 and 70709 can provide. This detector has been integrated into our 1.5 Inch Series female flanged housing.


用于光功率表的71889放大紫外光硅光电探测器采用光电模式工作，以获得最佳的直流和低频性能。这个标定的10毫米x 10毫米紫外硅探测器有185到1100纳米的范围，使光谱辐射测量得以进行。这个版本有一个内置的反阻抗放大器。放大器提供反式阻抗收益10 ^ 4 V / 10 ^ 9 V /。它还提供了三个可选择的时间常数设置，以匹配大多数实验需求的带宽上限。通过在最低带宽设置下工作，可以达到最低的噪声水平。这种放大后的型号需要+/- 15v直流电源才能工作，而70703和70709实验室电源可以提供。该探测器已集成到我们的1.5英寸系列女性法兰外壳。
