Lasermet's new ADM 1000 is a hand-held, easy-to-use high performance, laser power meter that has a sampling rate of 1MHz, meaning that users can measure peak power down to resolution of a few microseconds. This enables users to view waveforms and determine the power output of pulsed waveforms up to 400kHz in oscilloscope mode. As the ADM 1000 is calibrated (traceable to national standards) it can be used to accurately measure laser power outputs repeatedly.
Several heads are available for the device, such as an integrating sphere head suitable for measuring strobe light from a high powered LED source. A thermal head enables the meter to measure extremely accurate readings due to an accelerator circuit and thermal stabilisation electronics, which reduce drift and thermal interference. Standard photodiode heads are supplied with integrating spheres to reduce reflections to a minimum and for easy alignment and high accuracy, and the compact photodiode head is designed for limited spaces with no integrating sphere, the head depth being just 25mm.
A cursor facility enables users to select any number of points on single or multiple waveforms and determine the energy under the curve, and complex or irregular shapes can be selected to measure energy, power or time. Consequently, the ADM 1000 can measure peak power, average power, or energy. The device is portable, powered by a rechargeable 4.8V NiMH battery lasting up to 7 hours.
