Laurie (posted 2009-03-06 16:23:31.0) Response from Laurie at Thorlabs to andyh: Thank you for your interest in our power and energy meters. THORLABS offers a variety of power meter kits which include some of our most popular sensors bundled with the power meter console. I just lost power supply for PM100D. In case my e-mail does not come through, please send info to david.kortbawi@dkengineering.com Thank you, In that case, we obtain about 35 samples/sec (and a noisy signal). Help appreciated.This is a response from Nicola at Thorlabs. Just now the power meter can't read anything from the sensor and displayed Zero. Considering that time requested for ADC conversion is only 0.333 msec, the remaining 2 msec are entirely spent by the device firmware to process the data and could certainly be significantly reduced if two additional SCPI Commands, rather standard in this kind of instruments, were implemented also in your device: Thanks.This is a response from Meike at Thorlabs: Thank you for contacting us! But the given value is a calculation made from the measured optical power and the beams dimensions. I have contacted you directly to discuss the specifications and measurement procedure of your light source, as well as the programming to find a solution together.Using the SCPI commands in the manual I can communicate with the PM100D over USB to read the instantaneous power, which works well. Typical mounting configurations including post, cage, and lens tube options are available. This is not a standard item, so you wont find it on the website. This file is indeed missing from the example folder. I will contact you per email and send you the data. ADThis is an response from Michael of Thorlabs. I don't know the reason of this problem exactly, but I guess this problem was caused since we used these devices by connecting to PC. To display the power density in W/cm² in the right sub display it is necessary to enter the diameter of the incident beam or at an overfilled sensor the diameter of the sensor aperture. Thanks from SingaporeHi, we have a number of these in various labs, and we frequently use these to log optical power over long periods of time. If you wish to recalibrate only your power meter console, please contact Refer to the table to the right for the appropriate calibration service Item # that corresponds to your power meter sensor. Thank you very much for your inquiry. At the first time when we used these devices, there was no problem like this. Please reply quickly so that we can proceed with our research. Thorlabs PM100 Digital Optical Power Meter BMI. Irradiance you can also display with our power meter consoles by entering the beam diameter. we would like to know for the anaalog output of I will contact you directly to discuss further steps.We have the devices for a long time now and it seems the battery becomes bad (S/N P0000874) and (S/N PM001464)
Can you give me some advice; or the specific connecting or setting guide of those devices will be very helpful with me. As example, by issuing the SCPI command "READ?;READ?;READ?;READ?;READ?" Also, is there some plot of dark noise vs. temperature?a response from Julien at Thorlabs: thank you for your feedback! Thus, what is the range of sampling rate will we obtain? We will review your ideas and check how we can improve the units here. the coupling of the laser in the sensor, incorrect settings on the power meter or also tolerances in the power of the laser itself. So the voltage will change corresponding to the power of the incident light. You can also configure a number of samples to be taken and displayed, as well as an interval time between two averaging operations.Suddenly, Our PM100D cant recognize S121C. As you left no contact data, please contact us at europe@thorlabs.com for further questions.Does the software currently available (For both single and multiple devices) allow readings of 1kHz? Thank you.This is a response from Wolfgang at Thorlabs. The limitation here is due to the data transfer rate of USB. DaveThis is a response from Thomas at Thorlabs. We will release a beta version containing this feature at the beginning of the next week.Hi, As you left no contact data, please contact us at europe@thorlabs.com for further questions.Does the software currently available (For both single and multiple devices) allow readings of 1kHz? We are currently in the process of modifying the PM100 utility so as to allow the maximum possible sample rate (~1kS/s, hardware limited). Hope for your answer.
It depends on several optical parameters (pulse width, average power, beam diameter, repetition rate) if these sensors are suitable for your light source.
To ensure accurate measurements, we recommend recalibrating the sensors annually. I am sorry for this issue and have contacted you directly to troubleshoot this in detail.I'm using your device for the real time monitoring of few msec wide optical pulses, therefore I have the same problem as described in the previous message by gbeckford93. I contacted you directly for assistance.And I also want to know whether the device (S/N P0005229) is compatible with S120VC or not. thanks!This is a response from Stefan at Thorlabs. We will contact you directly with more detailed information.Dear Sir or Madam,
Neither our self-made labview program, nor the Thorlabs software is currently working anymore. But it just can't read after I stop pressing the sensor connector.
