USB-powered microjoule energy meter

LTB Lasertecknik has introduced a USB-powered, pyroelectric energy meter, sensitive to low energy pulses of 30nJ to 250μJ. The sensor features low background noise limit of 6nJ, and uses a 14-bit measurement dynamic.

All the function units for measurement acquisition, processing, settings, software calibration, digitalisation and storage are included into the compact measurement module.

Several modules can be operated in parallel via a PC. The measured values are displayed via the software. Each energy value gets a time stamp in the measurement module already, thus the energy values can be represented as function of time, or alternatively as a function of the pulse number. Export and statistic functions are provided for the evaluation of the measurements. In addition, correction factors can be entered when attenuators are used or transmission losses are to be evened out.

The μ-Joule Meter was developed for on-line monitoring in laser-induced industrial analytical applications and for medical diagnostics. Further application areas exist in the development of systems and methods, simultaneous monitoring of processes as well as system calibration and service.
