The PM100A Power Meter Console is the analog counterpart to thePM100D Digital Power and Energy Meter. It offers top performance and reliability in a compact and portable console. The PM100A 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. Depending on the connected sensor, it can measure optical power in the range from 100 pW to 200 W.

The PM100A is compatible with more than 20 photodiode,slim photodiode, integrating sphere, fiber, and thermal sensors designed for use from the UV to the Mid-IR. See theSensor Compatibility tab for further information. When used together with a sensor from the compact S15xC Series of fiber sensors, the PM100A becomes a compact and portable fiber power meter that is ideal for field applications as well as in the lab.Thorlabs offers a variety of Power Meter Kits which include some of our most popular sensors bundled with the PM100A and PM100D consoles. Additionally it allows the connection of unamplified anode grounded photodiodes with up to 5 mA photocurrent and thermal elements with up to 1 V output voltage.

Console Design
The compact housing has a large analog needle display with three printed scales and front panel backlit button controls. In addition, the PM100A features a bright LCD screen that displays four different digital readouts: absolute power, relative power, statistics, and a configuration menu. Audio tuning is also featured.

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 lower noise and better accuracy. Additionally, the power meter can adapt to the thermal time constant of thermal sensors leading to significantly faster measurements with thermal sensors. Thermal sensors have an individual time constant that can vary greatly from unit to unit. The PM100A now can adjust to this individual constant for each sensor and thus minimize the response time of the system (sensor + console).

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

Data can be recorded via the USB PC connection and the control software. The PM100A 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.
