Description
Whether your application requires measurement of low-power, high-power or energy of continuous or pulsed light sources, Newport’s Model 1835-C will do the job.

DC, peak-to-peak and pulse measurements can be displayed in units of W, dBm, dB, J, Ergs, A, and V.

Low-power measurements, in the 100 fW-2 W range, can be accomplished with any one of Newport’s 818 Series silicon, germanium or indium gallium arsenide semiconductor detectors, covering 190-1800 nm wavelengths.

High-power measurements, in the 10 mW-300 W range, can be performed with Newport’s 818T Series air-cooled thermopile detectors, enabling measurements in the 0.19-11 µm wavelength range.

Energy measurements of pulsed laser sources, from 35 nJ-1 J, can be taken with Newport’s 818J Series family of pyroelectric detectors, operating in the 0.19-20 µm wavelength range. Pulse repetition rates from single shot to 2 kHz can be accommodated.

Advanced features include a 2500 data point storage buffer; analog and digital filtering; programmable sample rates; moving statistics; and up to 10 recallable configurations.
