locations at a price-to-performance ratio second to none. Among all the other
practical tools provided, remote controlling with a computer and
synchronization to other instruments are simplified with the inclusion of
LabVIEW drivers, tools to develop in the .NET environment and a high-
speed software utility that fully utilized the optical meter’s ability to sample
at 250 kHz and transfer data via a Full-Speed USB interface (11 Mbps).
2.2 Optical Meter Functionality
Optical meters in the 1936/2936 Series product line are designed to provide
continuous wave (CW) and pulsed source measurements that support the testing
and production needs of free space beams and fiber optics based sources. These
optical meters come in one or two channel configurations. They require
detectors having a 15-pin D-Sub type Male connector.
2.3 Model 1936-R
The model 1936-R optical meter is a 1-channel input optical meter
compatible with all Newport detectors having a 15-pin D-sub type connector.
All product features and capabilities described herein are included in this
model, except a second detector channel.
2.4 Model 2936-R
The model 2936-R optical meter is a 2-channel input optical meter
compatible with all Newport detectors having a 15-pin D-sub type
connectors. All product features and capabilities described herein are
included in this model.
2.5 Calibration
Calibration of the power meter is done at the factory by defining a slope and
offset, for all ranges as determined for each detector type.
Newport recommends annual factory re-calibration to ensure the continued
accuracy of power meter measurements.
Please refer to the “Maintenance and Troubleshooting” section for contact
information for re-calibration of your power meter.
