Thorlabs' PM200 Touch Screen Power and Energy Meter, the latest addition to our power and energy meter console offerings, is the high-end counterpart to the PM100D and PM100A Analog Power Meter Consoles. It is equipped with a brilliant 5.7" color touch screen (118 mm x 88 mm) with VGA resolution that offers high contrast, a wide viewing angle, and a 90° flip screen that enables use in either a portrait or landscape orientation. The screen is encased in a compact, removable rubber housing that measures 170 mm x 125 mm x 38 mm.

The PM200 is compatible with all of our power and energy sensors (photodiode, thermal, and pyroelectric sensors) for use from the UV to the Mid-IR. It offers six current ranges for use with photodiode sensors (slim photodiode, microscope slide, integrating sphere, fiber) outputting currents from 10 pA to 5 mA and four voltage ranges for use with thermal sensors with thermopile voltages from 100 nV to 1 V. In both cases, manual and auto ranging are possible. The console has four manual voltage ranges for use with pyroelectric sensors with voltages from 100 µV to 100 V, and the auto-gain threshold can be adjusted from 0.1% - 99.9%. Customers can use their own custom built sensors and upload a response curve for spectral correction. Finally, a USB 2.0 port offers full remote control. Download an interactive Sensor Compatibility Guide for a complete overview over all compatible sensors and adapters.

Unique Features and Flexibility
The PM200 can load the spectral emmision curve for a broadband light source and calculate the net adjusted responsivity based on the spectral profile, allowing for more accurate power measurements. Similarly, the transmission curve for a filter can be loaded, and the meter will calculate the adjusted power and display the corrected value.

Other features that were implemented into the PM200 to extend its functionality and applicability include the following:

  • Data recording is stored to a large internal memory (128 MB) or a USB drive for stand-alone operation
  • Relevant laser beam specifications (e.g., peak power, power density, energy density, etc.) can be determined and sensors can be suggested based on inputted parameters (e.g., diameter, wavelength, power, energy, pulse length)
  • Software update using an external USB drive
  • Optional temperature and humidity module
  • Optional fiber inspection camera with power measurement capability will be available soon

The sensor's connector enables quick hot swapping of sensor heads and contains all the sensor information, including NIST traceable responsivity curves, sensor types, and model number. These details can be shown on the sensor information display screen. Diverse I/O ports enable quick integration into non-standard applications like an analog output, auxiliary input/output for external trigger, general-purpose programmable IO-ports, or ADC.

The S170C 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 350 nm and 1100 nm at optical powers between 10 nW and 150 mW. The sensor head's 76.0 mm x 25.2 mm footprint matches that of a standard microscope slide and is compatible with most standard upright and inverted microscopes.

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 1.5. 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.
