Thorlabs' Wireless Power Meters consist of an ultra-slim sensor connected to a portable power meter with a built-in graphical Organic LED (OLED) display. Versions are available with either a silicon photodiode (Item # PM160), thermal sensor (Item # PM160T), or high-power thermal sensor (Item # PM160T-HP). A rechargeable battery provides up to 20 hours of continuous operation and these power meters can be recharged through the USB port.

The PM160 power meter contains a sensitive silicon photodiode designed to detect optical powers between 10 nW and 2 mW at wavelengths between 400 and 1100 nm. The PM160 also comes with sliding neutral density filter that increases the maximum measurable optical power from 2 mW to 200 mW. The unit automatically detects the position of the neutral density filter to display the correctly calibrated power measurement. To use the filter, simply slide it up the handle until it locks into place over the detector.

The PM160T power meter uses the same thermal detector as our S401C High-Sensitivity Thermal Sensor Head. This power meter is designed to detect optical powers between 100 µW and 2 W at wavelengths between 190 nm and 10.6 µm. The PM106T-HP, on the other hand, is designed to detect optical powers between 10 mW and 70 W at wavelengths between 190 nm and 20 µm, offering a longer range and higher maximum power. Compared to photodiode sensors, these thermal sensors offer almost flat absorption curves, making them ideal for broadband power measurements. Combined with a wavelength range that extends into the mid-IR, the PM160T and PM160T-HP are well suited for use with a wide variety of sources including LEDs, SLDs, and mid-IR quantum cascade lasers.

These wireless power meters can fit into tight spaces and pick up an incident beam from any direction. The ultra-slim sensor end of the device connects to the handle with a joint mechanism that allows 270° of rotation (see the animation to the upper right). When rotating the sensor arm, there is a detent every 90° and enough friction in the joint mechanism that the sensor arm can be positioned at any angle within the allowed rotation range.

The output of the sensor is converted to a calibrated optical power measurement that can be displayed on the built-in OLED screen (see the screenshot to the right). The power meter can be controlled locally by the four buttons located on the sides of the OLED display's housing. The function of each button is indicated by the labels at each corner of the screen. The menus on the OLED display can also be used to rotate the text in 90° steps for ease of reading.

Alternatively, data can be transmitted using Bluetooth wireless technology or USB to an external device (see image to the left). A USB stick with an application for acquiring and displaying data on computers running Windows is included, as well as a driver set to support user-written applications in LabVIEW and C. The wireless power meter can also be operated from mobile devices; both Apple® and Android apps are available from their respective app stores.

Features

  • Operate up to Eight Power Meters Simultaneously
  • Record and Analyze Measurements in Real Time
  • Intuitive Analog Display and Graphing Modes
  • Configurable Long-Term Data Logging
  • Compatible with USB and Bluetooth® Connections

The Optical Power Monitor software GUI enables seamless control of up to eight power meters that are connected via USB or Bluetooth® wireless technologya. The latest software, firmware, drivers, and utilities for these power meters can be downloaded here

Multiple data measurement and analysis functions are integrated into the GUI package. The interface offers a user-friendly design with minimal use of color and low brightness that is ideal use in dark lab environments while wearing laser safety glasses. Measured data can be displayed in real time as a simulated analog needle, digital values, line graph, or bar graph. Continuously logged and short-term measurements can be recorded for data viewing and analysis at a later point. A built-in statistics mode analyzes measured data and continuously updates to reflect new measurements within the pre-determined measurement period.

The Optical Power Monitor software package installs the GUI, which then can be used to control the touchscreen, handheld, or USB-interface power meters. Firmware updates for supported power meters are also available. Programming examples and drivers for interfacing with our power and energy meter consoles using LabVIEW, Visual C++, Visual C#, and Visual Basic are installed with the software; refer to the manual for details. 

Please note that the Optical Power Monitor Software uses different drivers than the Power Meter Utilities Software and Thorlabs recommends using the new driver TLPM.dll. For users who wish to use the legacy Power Meter Software or use custom software designed using the older PM100D.dll driver, a Power Meter Driver Switcher program is included for easy swapping of the installed driver between the two versions. 

a. The PM160, PM160T, and PM160T-HP power meters are equipped with Bluetooth® connections.

Is it possible to sample and hold the Data or log a sequence without supervision with the wireless powermeter? - For example: We need to place the device into a sample chamber that is not accessible visually or via bluetooth and I want to be able to monitor the maximum value of exposure. Best regards!
wskopalik  (posted 2018-01-11 11:36:39.0)
This is a response from Wolfgang at Thorlabs. Thank you very much for your feedback. The power meters of the PM160 series do not have a logging function on the meter, but only in the software. The meters themselves only show the current power values. They can however be read out through a Bluetooth or USB connection and the software can log the measurement values for further evaluation. I will contact you directly to discuss your application in further detail.

eprend  (posted 2017-03-21 10:00:50.83)
I would appreciate it if the Solidworks information was available for the SM1 adapter that comes with the power meter. The 2D drawing does not provide enough information to reconstruct the part and after speaking with technical support there is no other way to get this part. Thorlabs is pretty good about having part information ready for download seems like it would be easy to construct this part so it is available.
swick  (posted 2017-03-22 04:56:54.0)
This is a response from Sebastian at Thorlabs. Thank you for the inquiry. The SM1-adapter which is included to PM160T is the same mechanical part as for our S130C-Series (SM1A29). The main difference is that for PM160T the adapter has a viewing target (fluorescent ring) made out of VRC6 instead of VRC1. As only the viewing target is different the CAD file of SM1A29 can be used: https://www.thorlabs.com/_sd.cfm?fileName=23425-E0W.sldprt&partNumber=SM1A29

It would be nice if there were an update for wavelength presets. We bought one and now, everytime we change the laser line, we have to dial in the new wavelength, which takes quite a bit. Would be great if there were like 5 or so presets, just like the big units offer.
shallwig  (posted 2015-07-28 08:39:20.0)
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. We are discussing if such feature can be implemented with the next update but due to its small design in terms of display size we have to make sure to arrange that in a way not to lose clarity. I would like to discuss that with you in in more detail but unfortunately you left no Email address, please feel free to contact me at europe@thorlabs.com

user  (posted 2014-12-01 16:08:04.653)
The iOS app I downloaded has the wavelength range max and min reversed. Thus it will not accept any wavelength I try to enter making the power meter almost useless. Didn't anybody actually try using the software before releasing it???
shallwig  (posted 2014-12-02 05:23:04.0)
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. Unfortunately we were not able to reproduce your problem neither with the first version nor with the updated version of the IOS App. By clicking on the wavelength symbol you should be able to enter the wavelength at which you want to measure directly. Alternatively you can set it by sliding the bar below to the desired value. As you left no contact information can you please contact me at europe@thorlabs.com to discuss this problem in more detail? Thank you.

What can the iOS app actually do? Is it as powerful as the windows GUI? Can i configure the wavelength and other things via iOS? Can it display a Graph? And if not, are there plans to implement this?
tschalk  (posted 2013-09-20 11:23:00.0)
This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. The iOS App is a tool to display the power measured by a PM160 wireless power meter on the screen of an iphone or ipad. It is not as powerful as the windows GUI and you are not able to store data or perform graphical analysis. The wavelength is able to be set via the App and can be used without a PM160 connected.

  • Ultra-Slim 3.5 mm Thick Sensor End (6 mm with ND Filter)
  • Includes Detachable SM05-Threaded Adapter

The PM160 Wireless Power Meter consists of a sensitive Silicon photodiode connected to a portable power meter with a built-in graphical Organic LED (OLED) display. The Ø9.5 mm (Ø0.37") sensor is designed to detect optical powers between 10 nW and 2 mW at wavelengths between 400 and 1100 nm. The PM160 also comes with a sliding neutral density filter that increases the maximum measurable optical power from 2 mW to 200 mW. The unit automatically detects the position of the neutral density filter to display the correctly calibrated power measurement. To use the filter, simply slide it up the handle until it locks into place over the detector.

Each individual PM160 power meter is calibrated to accurately convert the detected signal to the displayed power reading and a unit-specific calibration certificate is included. To ensure accurate measurements, we recommend recalibrating this power meter annually. Thorlabs offers the CAL-S130 recalibration service (listed below) for the photodiode in this power meter. Please contact Tech Support for recalibration information.

Three taps compatible with 8-32 and M4 screws allow the power meter to be post mounted in a variety of orientations. The device is shipped with an externally SM05 (0.535"-40) threaded adapter plate that slides over either the filter housing or the end of the sensor arm and snaps into place. When the adapter plate is attached to the sliding ND filter, the entire assembly can still be moved up and down the sensor arm. The external SM05 threads allow other components, such as fiber connector adapters (see the table to the lower right), to be attached directly to the PM160. We recommend operating the PM160 wireless power meter in environments between 0 and 50 °C (32 to 122 °F).

The PM160T Wireless Power Meter consists of an ultra-slim thermal sensor connected to a portable power meter with a built-in graphical Organic LED (OLED) display. The Ø10 mm (Ø0.39") sensor is designed to detect optical powers between 100 µW and 2 W at wavelengths between 190 nm and 10.6 µm. The almost flat absorption curve of the detector, maximum power of 2 W, and wavelength range that extends into the MIR make the PM160T well suited for use with a wide variety of broadband and MIR light sources, including LEDs, SLDs, and MIR quantum cascade lasers.

Each individual PM160T power meter is calibrated to accurately convert the detected signal to the displayed power reading and a unit-specific calibration certificate is included. To ensure accurate measurements, we recommend recalibrating this power meter annually. Thorlabs offers the CAL-S200 recalibration service (listed below) for the thermal sensor in this power meter. Please contact Tech Support for recalibration information.

Three universal taps compatible with 8-32 and M4 screws allow the power meter to be post mounted in a variety of orientations. The device is shipped with an externally SM1 (1.035"-40) threaded adapter plate with an MIR viewing target. This target is fabricated from thermochromic liquid crystal material and reacts to light from 1500 nm to over 13.2 µm. To install the adapter, place it over the sensor and secure it by tightening the setscrew with the included 0.9 mm (0.035") hex key. The external SM1 threads allow other components, such as fiber connector adapters (see the table to the lower right for recommendations), to be attached directly to the PM160T. We recommend operating this wireless power meter in environments between 0 and 50 °C (32 to 122 °F).

The PM160T-HP Wireless Power Meter consists of a slim thermal sensor connected to a portable power meter with a built-in graphical Organic LED (OLED) display. The Ø25.2 mm sensor is designed to detect optical powers between 10 mW and 70 W at wavelengths between 190 nm and 20 µm. The almost flat absorption curve of the detector, maximum power of 70 W, and wavelength range that extends into the MIR make the PM160T-HP well suited for use with a wide variety of broadband and MIR light sources, including LEDs, SLDs, and MIR quantum cascade lasers.

Each individual PM160T-HP power meter is calibrated to accurately convert the detected signal to the displayed power reading and a unit-specific calibration certificate is included. To ensure accurate measurements, we recommend recalibrating this power meter annually. Thorlabs offers the CAL-S200 recalibration service (listed below) for the thermal sensor in this power meter. Please contact Tech Support for recalibration information.

Three universal taps compatible with 8-32 and M4 screws allow the power meter to be post mounted in a variety of orientations. The device is shipped with an externally SM1 (1.035"-40) threaded adapter. To install the adapter, screw it into the internal SM1 threads on the sensor housing. The external SM1 threads allow other components, such as fiber connector adapters (see the table to the lower right for recommendations), to be attached directly to the PM160T-HP. We recommend operating this wireless power meter in environments between 0 and 50 °C (32 to 122 °F).
