A fast readout rate of samples per second allows active signal monitoring while the interface is in use. For precise measurements with thermal power sensors, these interfaces use nine voltage measurement ranges from 2 mV to 1 V, compared to only four ranges used by the PMUSB see the Specs tab. Please note that sensors are not included with these power meter interfaces.

For information about our compatible sensors, please see the sensor descriptions below. Alternatively, if you have a corresponding sensor that requires recalibration, you can include the power meter interface with the sensor for recalibration at no additional cost.

Also, we offer the USB-ABL cable as a replacement for the USB cable included with each sensor; this cable includes a locking screw to prevent accidental disconnects. Alternatively, thermal elements with a maximum output voltage of 1 V can be used. Alternatively, unamplified anode- or cathode-grounded photodiodes with currents up to 10 mA can be used.

Other energy sensors with voltage outputs from 20 mV to V can also be used. A fast readout rate of kilosamples per second allows active signal monitoring while the interface is in use. For precise measurements, these interfaces use thirteen voltage measurement ranges from 20 mV to V and 21 current measurement ranges from 2 nA to 10 mA, compared to only four voltage and six current ranges used by the PMUSB see the Specs tab.

Our C-Type standard photodiode , slim photodiode , integrating sphere , and fiber sensors can collectively measure optical powers from pW to 20 W. A readout rate of samples per second allows active signal monitoring while the interface is in use.

Alternatively, if you have a corresponding sensor that requires recalibration, you can include the PMUSB with the sensor for recalibration at no additional cost. These Slim Photodiode Power Sensors are designed to take optical source power measurements in locations where space and accessibility are at a premium. The 5 mm thin sensor end can fit between closely spaced optics, cage systems, and other arrangements where standard power meters may not fit.

A separately available SM1A29 adapter can be attached by 2 setscrews to any S series power sensor to mount fiber adapters, light shields, filters or any other SM1-threaded 1.

The SC Compact Slim Photodiode Power Sensor is designed to take optical source power measurements in locations where space and accessibility are at a premium. The 4. A separately available SM05A29 adapter can be attached by two 0. The adapter mounted on the SC power sensor is shown below.

The included data is determined with the help of a certified reference diode, which corresponds to the spectral range of the sensor to be calibrated. The SC Microscope Slide Power Sensor Head is a silicon photodiode sensor designed to measure the power at the sample in microscopy setups.

The silicon photodiode can detect wavelengths between nm and nm at optical powers between 10 nW and mW. The sensor head's The photodiode has an 18 mm x 18 mm active area and is contained in a sealed housing behind a neutral density ND filter with OD 1. A 20 mm x 20 mm indentation around the surface of the ND filter is sized to accept standard microscope cover slips. An immersion medium water, glycerol, oil may be placed in this well directly over the ND filter, or a cover slip may be inserted first to simplify clean up.

The gap between the photodiode and the neutral density filter has been filled with an index matching gel in order to prevent internal reflections from causing significant measurement errors when using high NA objectives with oil or water. The bottom of the sensor housing features a laser-engraved grid to aid in aligning and focusing the beam.

In standard microscopes, this grid can be used for beam alignment before flipping the sensor head to face the objective for power measurements. In inverted microscopes, turn on the transmitted illuminator to align the grid on the detector housing with the beam, thereby centering the sensor in front of the objective. Alternatively, the diffusive surface of the ND filter can be used as a focusing plane.

Sensor specifications and the NIST- and PTB-traceable calibration data are stored in non-volatile memory in the sensor connector and can be read out by the latest generation of Thorlabs power meters. We recommend yearly recalibration to ensure accuracy and performance. Please contact technical support for more information. Thorlabs also offers a Microscope Slide Sensor Head with a thermal sensor ; for complete specifications, the full presentation can be found here.

The thermal sensor can detect wavelengths between nm and The thermal sensor has an 18 mm x 18 mm active area and is contained in a sealed housing behind a glass cover. An immersion medium water, glycerol, oil may be placed over the glass cover plate. As seen in the image to the right, the bottom of the sensor housing features a laser-engraved target to aid in aligning and focusing the beam.

In standard microscopes, the target can be used for beam alignment before flipping the sensor head to face the objective for power measurements. In inverted microscopes, turn on the trans-illumination lamp and align the target on the detector housing with the beam; this will center the sensor in front of the objective. Thorlabs also offers a Microscope Slide Sensor Head with a photodiode sensor for low-power, high-resolution measurements; the full presentation may be found here.

These Integrating Sphere Photodiode Power Sensors are the ideal choice for power measurements independent of beam uniformity, divergence angle, beam shape, or entrance angle, making them excellent for use with fiber sources and off-axis free space sources. Our integrating spheres are designed for wavelength ranges from the visible through the NIR.

These sensors use either a silicon photodiode for detection in the - nm range or an InGaAs photodiode for detection in the - nm, - nm, or - nm wavelength range. The SC integrating sphere for 2. Compared to single-sphere designs, the two-sphere configuration improves device sensitivity by minimizing the internal sphere surface area while still effectively shielding the detector from direct illumination.

This design reduces the effect of input angle, divergence, and beam shape on the measurement result by effectively shielding the photodiode without the use of a baffle or other shielding mechanism. The externally SM1-threaded adapter can be removed using a size 1 screwdriver to place components closer to the window. NIST-traceable data is stored in the sensor connector. Thorlabs offers a recalibration service for these photodiode power sensors, which can be ordered below.

The compact sensor, integrated into the power meter connector, features a unique integrated design housing the photodiode sensor, fiber coupling, and NIST-traceable data.

Thorlabs offers two broadband thermal power sensors designed to measure low optical power sources with high resolution. Each thermal sensor's broadband coating has a flat spectral response over a wide wavelength range, as shown in the plot below.

For easy integration with Thorlabs' lens tube systems and SM1-threaded 1. The SC uses active thermal background compensation to provide low-drift power measurements. This is implemented through the use of two similar sensor circuits.

One sensor circuit is the type all thermal power sensors share: it measures heat flow from light absorber to heat sink. The other sensor circuit monitors the ambient temperature. It is located within the housing and measures heat flow from heat sink towards the absorber. The measurements of the two sensor circuits are subtracted, which minimizes the effect of thermal drift on the laser power measurement. For information about how the external thermal disturbances can affect thermal power sensor readings, see the Operation tab.

The broadband coating used on this thermal sensor offers high absorption at wavelengths between 0. The included, internally SMthreaded 0. The SC has internal SM05 0. These thermal power sensors are designed for general broadband power measurements of low and medium power light sources. All include an externally SM1-threaded 1. If replacing the heat sink, please note that the replacement must provide heat dissipation adequate for the application.

With the exception of the SC, all include an adapter with external SM1 1. All of these units are post-mountable for free-space applications and feature NIST-traceable data stored in the sensor connector. These thermal power sensors are unique in that they have thermal volume absorbers, where our other thermal power sensors have thermal surface absorbers. The volume absorber consists of a Schott glass filter. Incident pulses are absorbed and the heat is distributed throughout the volume.

In this way, pulses that would have damaged the absorption coating of a thermal surface absorber are safely measured by these thermal volume absorbers.

In comparison, the SC is faster, as the glass absorber volume is reduced and other design parameters have been optimized for speed. The SC and SC position sensors use thermopiles to obtain high-resolution measurements of a beam's position and power. The detector area consists of four thermopile-based sensors arranged as quadrants of a square.

The quadrants are mechanically coupled but electrically isolated; thus, heat is free to flow across the entire active area, but the signal from each quadrant measures the response in only that quadrant's thermopile. The XY position of the beam is determined by comparing the signal intensity measured for each quadrant. The SC detector is optimized for high sensitivity from 0. The SC detector is compatible with higher power levels from 10 mW up to 50 W.

The sensors can be controlled using the PM power meter console or PM series power meter interfaces. The system can be configured to display a visual trace of the position over time, a graph of the X and Y positions over time, a table of measurement statistics, or a simple numerical readout of the incident power. See the full web presentation and the PM manual for details. For information on recalibration services for these products, please contact Tech Support.

These Pyroelectric Sensors are designed to measure pulsed coherent and incoherent sources. Pyroelectric sensors are not suited for CW measurements, as they convert energy from light pulses into voltage pulses. A black broadband or ceramic coating is used for low or high power measurements, respectively. Thorlabs offers recalibration services for our photodiode optical power sensors.

Thank you very much for your inquiry. A Raspberry Pi usually works with a Linux-based operating system.

We can provide drivers for Ubuntu for the optical power meters which might be compatible with the Raspberry Pi operating system as well. Alternatively, you can e. So you could communicate with the power meter directly on this interface and would not need any additional drivers. I have contacted you directly to discuss these options in more detail. I have downloaded the the power meter utility 2. This is an response from Michael of Thorlabs. Although both drivers are included in the download, the new TLPM.

The driver can be changed with the tool, Driver Switcher. I have contacted you directly to discuss further details. This is in response to the question by "Moritz Jung posted This is a response from Michael at Thorlabs. Thank you very much for this feedback and for completing this information. Can you give any details on how this is supposed to be done? Is it possible to use the OPM software without changing the driver? But I would prefer sticking to the up to date drivers.

Thanks for your answer! Afterwards the driver functions can be used together with the SCPI commands for communication. I use a SC detector connected to PM and I observe the AO1 fast analog output of the power meter via an oscilloscope as I apply a square current pulse to a laser diode.

This is very different than the KHz bandwidth in the PM specs. What is a typical rise-time that I should expect from SC?

Are there other detectors compatible with PM which would lead to faster rise times? If there is a special setting that I need to apply to observe KHz level signals could you let me know? Thank you.

Dear Ekin, Thank you for your feedback. The behaviour you are observing is due to a firmware bug which always kept the bandwith on low status. We corrected this issue with the last firmware update which we will provide on our website ASAP. I reached out to you in order to provide further assistance.

Hello I have been using PM interface with a thermal sensor. I was wondering, do you have any Python support files for PM? I contacted you directly to send you the necessary information to control the PM in Phython. I contacted you directly to provide further support and to send you the desired status register for the PMUSB. In general, it is better to manually set the measurement range beforehand.

Thank you very much for the feedback. Depending on the wavelength of the measured light and the sensor used, it is essential to set the wavelength in the Optical Power Monitor software to compensate the measurement result for the wavelength-dependent sensitivity of the sensor. Therefore, when measuring DLP projectors, it is a good solution to adjust the settings manually. In general, it is recommended to use the default Auto Range ON setting.

Auto Range OFF allows you to set the measurement range manually, which is recommended for measuring pulsed light sources, for example.

The description under 'software' for the PMUSB says 'visual basic' examples are included with the driver. They are not, just C and C are included. Thank you for the note. You are right about the fact that Visual Basic examples are not installed with software and drivers. We will correct the statement on our website.

Do you plan to implement this command in the near future? Thank you for sharing your findings with us. We will look into this. At the time we do not plan to change the SCPI command set.

Hello, We're writing custom software that we need to work on multiple operating systems, including Linux and macOS. Are there still no drivers or other tools that would enable development for those operating systems? If writing our own drivers is the only option, where could we get complete documentation? Thank you! For Linux we can provide shared objects but for macOS we do not provide drivers at the moment. I contacted you directly to get further information about the operating systems you work with.

We use PMUSB and PMD frequently for measurements with Thorlabs sensors and for measurements with our own photodiodes - the ability to use a custom sensor is very useful to us. Thank you for your suggestion. We are already working on the realization of such a device. I will contact you directly with further information. Thank you for the feedback.
