Extreme Versatility and Great Value |
This new 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.
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 type. |
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. |

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.Users can change the display mode to analog, for fine adjustments. |

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 can be accomplished with any one of Newport’s 818 (see Low-Power Photodetector, 818 Series) and higher-end 918D Series UV, Silicon (Si), Germanium (Ge) or Indium Gallium Arsenide (InGaAs) Detectors, covering 190–1800 nm wavelengths (see Low-Power Photodetectors, 918D Series). 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 Optical Detector Selection Guidefor a power meter/detector compatibility chart. |
Compatible with 818P Thermopile and 818E Pyroelectric Detectors |
High-power measurements, in the 1 µW to 20 kW range can be performed with the 1928-C Series meters utilizing thermopile detectors (see Thermopile Detector Sensor, 818P Series), operating in the 0.19-11um wavelength range. Energy measurements of pulsed laser sources, from 7 µJ to 20 kJ can be taken with pyroelectric detectors (see Pyroelectric Detector Sensor, 818E Series) 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. |
Advanced Measurement Capabilities |
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. |
|
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. |

Choose the proper color for maximum visibility over the laser eyewear
|
Environment-Friendliness |
The most sophisticated optical meter circuitry meets environmental consciousness. The 1928-C consumes a fraction of electrical power compared to any industry standard benchtop instruments, and there is no need of a cooling fan, which further decreases power consumption. The optical meter is also featured with a Stand-by mode, where the user can put it into a sleep mode and activate it again with a press of any button on the front panel. |
