Energy Measuring Module for pulsed lasers
- High sensitivity (30 nJ)
- Pyroelectric sensor
- Several modules simultaneously usable on a PC
The USB-powered energy meter works on the basis of the pyroelectric measurement principle. It can be used for measuring very small pulse energies (30 nJ - 250 µ-J) and it is characterized by a very low background noise limit of 6 nJ. The measurement dynamics is 14 bit.
All the function units for measurement acquisition, processing, settings, software calibration, digitalization and storage are included into the very compact measurement module.
Several modules can be operated in parallel on 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 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.
Besides all current light fibers the free beam can also be measured.
The µ--Joule Meter was developed for on-line monitoring in laser-induced industrial analytics and medical diagnostics. Further application areas are the development of systems and methods, simultaneous monitoring of processes as well as system calibration and service.
Modern measurement methods require very small energy amounts in order to initialize the measurement process. On the same time their dosage and evaluation become ever more important. The µ--Joule Meter is ideally suited for this due to its high sensitivity, the linearity on all the measurement ranges, its ideal insertion dimensions and its long-term stability.
