Extreme Versatility from State-of-the-Art Electronics

For applications requiring measurement of low-power, high-power or energy of continuous or pulsed light sources, Newport’s 1936-C/2936-C instruments have broken the barrier of temporal measurement performance with calibrated results. This series of power/energy meters have the ability to handle repetition-rates of up to 10 kHz at an unheard sampling rate of 250 kHz. This means that even reasonably high speed dynamical phenomena can be seen using the meter, eliminating a need for an oscilloscope in many cases.

Pulse, peak-to-peak and DC source measurements can be displayed in units of W, dBm, dB, J, A, and V. Simultaneous measurements of a variety of light sources operating at different power levels and wavelengths can be performed with our Dual-Channel 2936-C Series Optical Meters.

Compatible with 818 and 918D Series Semiconductor Detectors

Low-power measurements, of pW to several Watts can be accomplished with any one of Newport’s 918D Series Silicon (Si), Germanium (Ge) or Indium Gallium Arsenide (InGaAs) Detectors, covering 190–2550 nm wavelengths (see Low-Power Photodetectors, 918D Series). All 918D Series Detectors have a built-in temperature sensor utilized for sensing and actively compensating for temperature-induced measurement fluctuations.

Working with 818P High Power and 818E Energy Detectors

High-power measurements, in the 1 uWatt to 20 kWatt range can be performed with the 1936/2936-C Series meters utilizing thermopile detectors, operating in the 0.19-11um wavelength range. Energy measurements of pulsed laser sources, from 7 uJoule to 20 kJoules can be taken with pyroelectric detectors operating in the 0.19–20 um wavelength range. Pulse repetition rates from single shot to 10 kHz can be measured directly with these instruments, without having to rely on oscilloscope measurements.

Advanced Measurement Capabilities

True Root-Mean-Square (rms) measurements, providing the most accurate rms value regardless of the shape of the input waveform.

Frequency measurements can be performed in the 1Hz to 250kHz range using Newport's Low Power 918D and 818 Series detectors and 818E Pyroelectric detectors.

Additional advanced features include user defined display colors, an internal 250,000 data point storage buffer, additional data storage using an external USB flash drive, analog and digital filtering, programmable sample rates, moving statistics, plotting and multiple user-configuration storage.

Choose the Display Color for Your Needs

Users can select from 6 display colors to match their specific lighting conditions and colors of their laser safety eyewear. Measurements can also be displayed in various display formats, such as numeric, graphic, bar and strip charts.
