The measurement optics of the MSM are selected individually, depending on the beam source to be measured. Crucial factors here are the wavelength (248 to 1090 nm) and the enlargement determined by the focal diameter (3:1, 5:1, 15:1).
The dynamic range of the integrated CCD sensor is expanded via an exposure time control to over 130 dB, enabling measurement of caustics over more than 4 Rayleigh lengths, as required by ISO 11146. The MSM can be supplemented with an optional filter wheel fitted with a neutral density glass filter (OD1 to OD5). This filter wheel enables the measurement of power densities in the range of a few W/cm² up to several MW/cm2 without the system having to be modified.
Two alternatives are available for the operation and control of the MSM:
- The PC-based LaserDiagnosticsSoftware LDS makes it possible to measure the beam distribution in the focal area manually and semi-automatically and to determine the beam position and beam dimensions.
- Scripts semi-automatically control the MSM, for example for repetitive measurement problems in servicing, quality assurance and acceptance inspection. They are individually adapted to the measurement process at hand. Advantage: Through programmed user guidance, the requirements for operating the MSM can be significantly reduced.
