Integrated LED illumination
A highly intensive and homogeneous LED illumination is integrated directly in the frame of the sensor housing. The illumination is therefore always optimally aligned on the sensor. Cumbersome calibration and alignment of external light sources is unnecessary. Another advantage is that an additional power supply can be omitted.
For inspection tasks in transmitted light or in special lighting specifications, our sensors are also optionally available without integrated LED illumination.
In conventional line scan cameras, the image is distorted towards the edge by the lens used. The Line Scan Bar, however, guarantees a distortion-free 1:1 copy of the object. This is achieved by means of a specially designed array of rod lenses, GRIN lenses, with a defined working distance that produce the necessary telecentric captured radiation. This is an optimal prerequisite for the quality inspection of problematic surfaces. Furthermore, it also eliminates the need for time-consuming alignment or focus during the commissioning.
The Mitsubishi Electric - Line Scan Bar uses CMOS high-end chips for high-speed image acquisition, a defined pixel size of 0,042 mm and real trilinear CMOS chips with RGB filters.
For applications in which no RGB image is necessary, a monochrome CIS sensor is also available.
Due to its very compact design, the sensor only requires a fraction of the space that a system still based on line scan cameras would need. This allows system integrators and machine manufacturers more installation options when integrating the sensors in machines or systems - and important cost savings.
Easy mounting and installation
The Line Scan Bar is mounted to the side of the machine wall by just four screws at a working distance of 12 mm from the protective glass surface. Then the power cable and the data cable are simply plugged in, and assembly is completed. Time-consuming calibration, alignment or other settings are no longer necessary. The Line Scan Bar is pre-calibrated at the factory with a white/black correction. Compared with the assembly of a normal line camera system, a time-saving of up to two days assembly time can be achieved with the Line Scan Bar from Mitsubishi Electric.
Low service costs
Thanks to its easy installation, any replacement of the Line Scan Bar that is required can be done by the in-house technicians. There are no costs for deployment of service staff. Here also, there is an enormous savings potential for the end-user and the system integrator or machine manufacturer.
