The PM100D is the cornerstone of Thorlabs' optical power and energy meter consoles and is the digital counterpart to the PM100A Analog Power Meter Console. The console (and sensor, sold separately) is ideal for use as a CW and pulsed laser power meter, incoherent optical source power meter, general light power meter, fiber power meter, and more.

The PM100D is compatible with more than 25 photodiode, slim photodiode, integrating sphere, fiber, thermal, and pyroelectric sensors designed for use from the UV to the Mid-IR. See the Sensor Compatibility tab for further information. Thorlabs offers a variety of Power Meter Kits which include some of our most popular sensors bundled with the power meter console.

Console Design
The compact housing has a large, 4” backlit display with a resolution of 320 x 240 pixels and illuminated buttons, all of which make operation in dark labs easy. The LCD’s clear GUI offers easy data readouts with an intuitive navigation scheme. Interactive tooltips help to operate the device by giving the user step-by-step operating instructions, displaying the next step on the screen.

The PM100D features four standard measurement screens. The first option is a numeric readout useful for standard power and energy readings. The second option is a tuning needle typically seen on analog devices, however optimized to run as a digital readout on the display screen. Third is a tuning graph, which is very convenient for fine tuning CW and pulsed laser sources.

The unit can also be run in a data acquisition mode. Simply start the scan and the unit automatically starts recording data such as current power/energy, minimum, maximum, standard deviation, and other important statistics recorded over the acquisition period. The PM100D also features several user customizable displays and audio tuning for use when the detector is not within visual range. See the Display Screens tab for further information.

Connectivity
The sensor connector, shown to the right, enables "hot swappable" quick sensor exchange. The sensor connectors contain all the sensor information including NIST-traceable responsivity curves, sensor types, and model number.

A slot for an SD memory card (a 1 GB SD card is included) allows data recording even in stand-alone operation, giving the user large memory storage when recording data in the field or away from a computer in the lab. Data can also be recorded via the USB PC connection and the control software. The PM100D software is capable of handling up to six consoles simultaneously. PC control software and features are highlighted in the Software tab.

In addition to remote control operation and data logging/recording, the USB connection can also act as the charging system for the Li-Polymer battery. Also included is an AC battery charger which uses an intelligent charging management system to improve battery lifetime and reduce battery memory effects.

A selectable bandwidth of either 20 Hz or 100 kHz offers more flexibility and adaptability to specific measurement tasks while using photodiode sensors. The higher bandwidth is optimal for pulse-detection; the lower bandwidth offers better accuracy. Power and energy density can also be displayed based on user input beam areas. Optical sources may be attenuated / gained electronically through the console. Note: Attenuating the source through the console will not attenuate the light at the detector and damage may still occur above the detector threshold power.

Thorlabs' complete line of Sensor Heads are shown below. Utilizing the variety of sensors, the PM100D can measure optical power and energy from CW and pulsed sources. Sensors are available for monitoring low power CW laser diode emission to high power excimer, YAG, and CO₂ laser pulses.

The PM100D can be used in the lab, as well as in the field with our fiber coupled sensors. Please see the Applications tab for a small sample of possible configurations. Contact tech support with any applications based questions.

Additionally, the PM100D communicates with the sensor and accesses spectral response functions, time constants, and other information specific to the detector. The PM100D then corrects for spectral response functions automatically. The power meter also accounts for the detector time constants (which can vary greatly, especially for Thermal sensors) for each sensor and can minimizes the response time of the system (sensor + console), thus greatly improving the efficiency of the unit.

The PM100D is available as a kit, bundled with our most popular sensors. Please visit our PM100D Kits page for more info. If you have any questions regarding these kits, or would like to suggest other kit options, please contact our tech support department for more details.
