Optical Power Meter

A drop in replacement for the existing 1830-C model, the 1830-R optical power meter from Newport can be used in fiber optic component production and testing. DC power measurement can be displayed in units of W, dBm, dB, and relative measurement on the 4 ½ digit annunciated LED, providing a wide dynamic range with power sensitivities down to 10 pW and detector dependent full scale readings up to 2 W. Relative power measurements, in reference to a previously stored value, is performed with the result displayed either as a ratio or dB. The meter comes with a standard USB2.0 interface, while the 1830-R-GPIB model offers additional IEEE-488 (GPIB) and the RS-232C ports. Both the 1830-C and the current 19xx-C commands are supported. A built-in beeper, which changes its frequency as a function of incident optical power, can be utilized to optimize optical beam alignment. The analog output that provides a voltage proportional to the detector current can be used for fast control loop applications.
