The
Model 1830-C Power Meter is a high-resolution autoranging picoammeter
compatible with all of Newport’s 818 Series low-power
Si, Ge and InGaAs detectors. It is the most popular Newport
model used in production testing of fiber optic components.
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.
