1918-R光功率計/能量計的詳細(xì)說明：
The new 1918-R Optical Power Meter/Energy Meter, a RoHS compliant version of 1918-C, is the hand-held optical power meter of choice for applications requiring the measurement of continuous intensity or pulse energy of light sources. This state-of-the-art portable optical power meter leverages the advanced features and display capabilities of Newport's 1936-C Optical Power/Energy Meter into a compact, wall-plug and battery powered device, for use in the lab or in the field. The 4 inch, full color, graphical LCD display enables both numerical and graphical measurement representation, with a selection of various color palettes to match filtering properties of users’ laser eye safety goggles. The 1918-R optical power meter has the ability to handle peak-to-peak measurements of pulses with repetition-rates of up to 4 kHz at a sampling rate of 250 kHz. Pulse, peak-to-peak and DC source measurements can be displayed in units of W, dBm, dB, J, A, V and Sun depending on the detector types used.
Please reference our power meter selection guide: power meter selection guide.
