Page 18 Power Meter Driver Switcher 4.2.3.1 User Calibration of Sensors The OPM provides a Calibration Wizard for the user to calibrate Thorlabs Photodiode and Thermopile Sensors in combination with a power meter. In principle, the Calibration Wizard uses a measured single point signal from a trusted reference sensor to calibrate the sensor connected to the power meter.
Page 19 The wizard leads the customer through the protocol. The start screen allows to choose between the factory calibration and a user calibration. Click "Perform User Calibration" to start a calibration or select and apply a previously saved calibration. © 2023 Thorlabs...
Page 20 To start a new calibration, define the user and click NEXT to adjust the background noise "Zero Adjust". Follow the instructions and click "START". The background is measured. This can be repeated. When the background measurement is finished, click "NEXT" to proceed to the calibration. © 2023 Thorlabs...
Page 21 When the calibration is done the following screen appears. To ensure that the calibration is within a reasonable range, the calibration is limited to values differing less that 20% from the reference values. An error message appears if the sensor that is calibrated is out of range. © 2023 Thorlabs...
Page 22 Click "NEXT" to write the calibration data in the internal memory of the power meter and save the results as a .pdf file on the PC. To take a second measurement at, for example, a different wavelength, click "Add Entry". © 2023 Thorlabs...

Page 65 Internal Binning With Dead Time Gated In Gated mode, an external device provides an Active High TTL Signal to define the binning. The OPM software in Gated mode provides adjustment via the following interface with the parameters described below: © 2023 Thorlabs...
Page 66 Threshold [%] defines the signal level above which signal is counted. This function can be used to eliminate afterpulsing. The default settings for the threshold are optimal for the Thorlabs SPDMA and SPDMHx single photon detectors. To compensate for afterpulsing in other detectors, first determine the afterpulsing characteristics of the connected single photon detector and then set the threshold level.

Page 69 Be aware that the driver assignment of the power meters is changed upon installation of the OPM. If you created your own software for remote operation of Thorlabs power meters based on the PM100D.dll driver, the software needs to be modified to use the new TLPM.dll driver. Please read...
Page 70 Use the PM100D.dll for the Power Meter Monitor, Optical Power Meter Utility, or Multi Power Meter software. The OPM can operate with either driver. However, some functions of PM101x, PM102x, PM103x, and PM400 will not appear when using the PM100D.dll. © 2023 Thorlabs...
Page 71 7 Instrument Driver for Thorlabs Power Meters The Help panel guides you to the Thorlabs website, the license agreement, and the software version number. Close the Power Meter Driver Switcher after the driver exchange to prevent unintentional use. Note You can use the different drivers for different devices in parallel. Example: Power Meter PM100USB SerialNumber 1 and Power Meter PM100USB SerialNumber 2 are both connected to the PC.
Page 72 The driver assignment of the power meters is changed upon installation of the OPM. If you created your own software for remote operation of Thorlabs power meters based on the PM100D.dll driver, the software needs to be modified to use the new TLPM.dll driver.
Page 73 · I can not use the software Power Meter Monitor Ø Reason: The Thorlabs Optical Power Monitor (OPM) uses a different driver for the connected power meters than the Thorlabs Power Meter Monitor. The instrument driver of the power meters was changed to the new driver upon installation of the Optical Power Monitor.
Page 74 Instrument Driver for Thorlabs Power Meters · I can not use my Custom Made Software to steer Thorlabs power meters anymore Ø Reason: The Thorlabs Optical Power Monitor (OPM) uses a different driver for the connected power meters than former Thorlabs power meter software applications.
