The 1928-C benchtop optical meter delivers unrivalled performance at a very competitive price for a benchtop optical meter. It can measure pulse, peak-to-peak and DC source measurements in units of W, dBm, dB, J, A, V, Sun, and relative units (depending on the detector used), either directly or as a measurement relative to a reference value. Its 4-inch full color, graphical LCD display enables both numerical and graphical representations of measurements.
This single channel benchtop optical meter is extremely versatile and sensitive, capable of measuring optical power ranging from 11 picoWatts to 20 kWatts, and optical pulse energy from 7 µJ to 20 kJ. All 918D Series semiconductor-based low power, 818P Series thermopile, and 818E Series pyroelectric detectors are fully compatible with the instrument and hot-swappable; there is no need of recycling the power when a different sensor has to be used.
The 1928-C optical meter is also equipped with several green features: the meticulously designed circuitry allows much lower energy consumption compared to the 1936-C model, eliminating the need for a cooling fan. It also features a Stand-by mode for further energy savings when the meter is not being used actively. The optical meter can be activated again with the press of any button on the front panel. Finally, the meter can display irradiance in ‘Sun’ units, enabling photovoltaic researchers to use the power meter as a complementary tool to a reference solar cell.
Note: For compatibility with Oriel Photomultiplier Tubes and Detectors, Oriel housing 70690 and power supply 70705 will need to be purchased.

Extreme Versatility and Great Value
Now being offered at 20% off regular price! See ordering tab for more information.
This optical meter features many of the great features available in Newport’s hugely successful 1936-C/2936-C Series, with an attractive pricing. For applications requiring measurement of low-power, high-power or energy of continuous or pulsed light sources, Newport’s optical power meters have broken the barrier of temporal measurement performance with calibrated results. The 1928-C power/energy meter has the ability to handle repetition-rates of up to 4 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.
Fine Adjustment with the Analog Gauge mode
Users can change the display mode to analog, for fine adjustments. Zooming and selectable filtering, combined with fixed or auto range, gives the users an unprecedented level of flexibility. This is an ideal feature for laser alignment.
Analog Gauge display
In the Graph screen mode the power meter acts as an oscilloscope. Users can see in real time the optical power level in their experiment.
Graph screen
For users who would like to fine adjust a maximum or a minimum, the 1928-C offers the Analog Bar display mode with Auto Zoom function.
Compatible with Photodiode Detectors
Low-power measurements, pW to several Watts (detector dependent) can be accomplished with any one of Newport’s 818 (see Low-Power Calibrated Photodiode Sensors) and higher-end 918D Series UV, Silicon (Si), Germanium (Ge) or Indium Gallium Arsenide (InGaAs) Detectors, covering 200–1800 nm wavelengths (see Low-Power Calibrated Photodiode Sensors). The 918D Series Detectors have a built-in temperature sensor utilized for sensing and actively compensating for temperature-induced measurement fluctuations, making them the most advanced photodiode based detectors. Please see Low Power Sensor Selection Guide for a power meter/detector compatibility chart.
Newport's 918D series Low-Power Calibrated Photodiode Sensors low power photodiode sensors are a great addition to your measurement setup.
Compatible with 818P Thermopile and 818E Pyroelectric Detectors
High-power measurements, in the 1 µW to 20 kW range (detector dependent) can be performed with the 1928-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 µJ to 20 kJ (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 6 kHz can be measured directly with these instruments, without having to rely on oscilloscope measurements.
Newport's 818P Thermopile Laser Power Sensors, Newport Compatible general purpose detectors meet the most demanding laser power measurement needs.
Advanced Measurement Capabilities
The 1928-C 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.
True Root-Mean-Square (RMS) measurements, providing the most accurate RMS value regardless of the shape of the input waveform.
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.
