The Model 1830-C Power Meter is a high-resolution autoranging picoammeter compatible with all of Newport’s 818 Series low-power silicon, germanium and indium gallium arsenide detectors. DC power measurements can be displayed in units of W or dBm on the instrument’s 4 1/2 digit annunciated, backlit, wide-angle view LCD, providing wide dynamic range with power sensitivities down to 100 fW and full scale readings up to 2 W, with the OD-3 calibrated optical attenuator. Relative power measurements, in reference to a previously stored value, can also be performed with the result displayed either as a ratio or in dB. A built-in beeper, which changes its frequency as a function of incident optical power, can be utilized to optimize optical beam alignment. This system also has an analog output that provides a voltage proportional to the detector current, which can be used for recorder or control loop applications.
