NEWPORT’s newly designed 1830-R optical meter is a ‘drop-in’ replacement for the 1830-C power meter, which is widely used in fibre optic production and testing.
DC power measurements in units of W, dBm, or dB are displayed on the 4½ digit backlit LED display. The dynamic range of the meter covers 11 orders of magnitude, with sensitivity down to 10pW and full scale readings up to 2W, depending on the detector used. The unit has an audible beeping tone which changes frequency as a function of incident optical power, which Newport says is useful when optimising the alignment of an optical beam.
Other features include a USB 2.0 interface (1830-R) and additional IEEE-488 (GPIB) / RS232C outputs (1830-R-GPIB). For convenience, two analogue output modes – 2V into 1MOhm and 1V into 50Ohm impedance – are also provided. The enhanced 1830-R (-GPIB) optical p0wer meters are hot-swappable among detectors, such as the low-power 818-series and the higher-sensitivity 918D photodiode detectors. The ultraviolet (UV), silicon (Si), germanium (Ge), or indium gallium arsenide (InGaAs) detectors operate in the 200-1800nm wavelengths.
Newport says its 1830-R is CE- and RoHS-compliant, and available now. Each unit comes with software and documents included on a USB memory stick.
