Optical Power Meter mainframe (1830C)

DC power measurements can be displayed in units of W and 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. Various detector accessories allow for free-space, as well as for fiber coupled power measurements.

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.

RS-232C and IEEE-488 (GPIB) interfaces are both provided as standard features, allowing the remote control of the instrument with a personal computer. Sample LabVIEW drivers are provided upon request.

Additional features include wavelength adjustment in 1 nm steps from the front panel, and an analog output that provides a voltage proportional to the detector current, to be used for recorder or control loop applications.
