New! 1936-R and 2936-R, the RoHS compliant version, are available now! 1936-C and 2936-C will be no longer available upon depletion of the remaining stock.
The 1936-R and 2936-R optical power and energy meters are one of the most sophisticated optical meters available in the market. With patented methods for measuring optical signal characteristics the hugely successful 19xx-C/R power meter series has set a new level of standards in optical power and energy measurements. These new instruments are born by combining the superb femtowatt level sensitivity reached by the legacy 1931-C/2931-C series and the extreme versatility of the 1935-C/2935-C series, resulting in a truly revolutionizing breed. No matter what the applications are and how demanding the measurements are, you only need one of these and Newport detectors. 918D and 818 semiconductor-based low power, 818P Series thermopile, and 818E Series pyroelectric detectors that have a DB15 connector or adapter are fully compatible with the instruments. The detectors are hot-swappable, so there is no need to cycle power when a different sensor has to be used.
Note: For compatibility with Oriel Photomultiplier Tubes and Detectors, Oriel housing 70690 and power supply 70705 will need to be purchased. Please see Related Products tab for additional information.

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/R and 2936-C/R 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, V and Sun (depending on the detector model). Simultaneous measurements of a variety of light sources operating at different power levels and wavelengths can be performed with our Dual-Channel 2936-R Optical Meter.
The 1936-C/R and 2936-C/R also offers an Analog Gauge display mode ideal for tuning applications.

Compatible with 818 and 918D Series Semiconductor Detectors
Low-power measurements, of pW to several Watts (detector dependent) can be accomplished with any one of Newport’s 918D Series Silicon (Si), Germanium (Ge) or Indium Gallium Arsenide (InGaAs) Detectors, covering 200–1800 nm wavelengths (see Low-Power Calibrated Photodiode Sensors). All 918D Series Detectors have a built-in temperature sensor utilized for sensing and actively compensating for temperature-induced measurement fluctuations.
Compatible with 818P High Power and 818E Energy Detectors
High-power measurements, in the 1 uWatt to 20 kWatt range (detector dependent) can be performed with the 1936/2936-C Series meters utilizing thermopile detectors (see Thermopile Laser Power Sensors, Newport Compatible) operating in the 0.19-11um wavelength range. Energy measurements of pulsed laser sources, from 7 uJoule to 20 kJoules (detector dependent) can be taken with pyroelectric detectors (see Pyroelectric Laser Energy Sensors, Newport Compatible) 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
The 1936-R and 2936-R software gives users the flexibility of a command line environment as well as the ability to download collected data directly to a computer for analysis.
Software command line display
You are just a few clicks away from installing Newport's latest Labview samples onto your computer (see Literature and Downloads tab). Labview, CSharp and C++ samples will be installed after a full install of the software. Software for the 2936-C/R is compatible with the 1936-C/R.
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 detectors and 818E Pyroelectric detectors.
Additional advanced features include a Stand-by mode for energy savings, 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.
