Data Matrix is a 2-D matrix code, that contains dark and light square areas.
It has a reference pattern of two continuous lines and two alternation dark and light "dots" on the perimeter of the code.
Typically CCD based camera devices ("data matrix readers") are used to scan the codes.
Data Matrix is used for reduced dimensions items, and allows the storage of a large ammount of information, by a large variety of printing and marking technology.
It is worth to note that the Data matrix codes have a certain degree of redundancy, being then less prone to errors, in case some part of the code is lost. This characteristic is key for critical applications, like in drug industry.

In order to remove parasitic emitter diffusion around wafer edges of Solar Cells, laser technology is gaining more and more interest. The technique is fast, suitable for inline process, and contactless for safe handling of thin solar cell wafers. We have developed a very efficient process that makes use of high power, high quality single mode laser emitting at 355 nm, resulting in a process as fast as 1.5 s/cell, with isolation efficiency as high as 99% (as mesured by LBIC technque).

Laserpoint offers laser micromachining and marking solutions at various levels, from components to subassemblies ready for OEM integration, to Class I solutions. Laserpoint integrates exclusively the top of the range of technologies, from hig performance fiber lasers up to ultrashort pulse laser devices.
