Mitsubishi Electric - Line Scan Bar

The Mitsubishi Electric Line Scan Bar is an elegant alternative in high-resolution and high-speed applications which would usually require a set of several line scan cameras. Line Scan Bars are very compact, energy saving and easy to install and maintain. The integration of a LineScan Bar into an existing machine setup is usually straight forward and requires only minimal head room. The time consuming alignment of several line scan cameras to each other and to the illumination is no longer required.

The Mitsubishi Electric Line Scan Bar series of contact image sensors combine camera, optics and illumination in a single device. Built-in timing control includes encoder inputs and light control and is configurable. This helps in setting up the system quickly and easily and save the effort of aligning and programming all components individually - allowing for the faster commissioning of the whole system. It also reduces the risk of defective components and repair-related downtimes, increasing the operating time of the system.

The Mitsubishi Electric Line Scan Bar series include firmly built-in camera, illumination and optics all in a single device. Even in the harshest manufacturing environments with shocks and vibrations, all machine vision components will stay stable and consistently aligned.

The principle of contact image sensors is based on a very compact design with short working distances. The overall system is much smaller than conventional line scan camera systems. This is particularly important to integrators and machine builders for designing and budgeting compact new image processing modules. At the same time, the minimal space requirement also allows hassle-free integration into existing facilities. New applications can be realised, which have not been possible until now due to the size of line scan camera setups or complex mounting solutions.

The LineScan Bars incorporate a particularly designed field of cylindrical lenses (GRIN lens) with a fixed working distance. The telecentric ray guidance guarantees a 1:1 image without any optical distortions. This is an ideal precondition for quality inspection tasks on difficult surfaces. Alignment or focussing of optical components can be omitted when integrating line scan bars. This can save days of mechanical effort. In addition, accidental maladjustment, which can lead to a machine downtime, isn't possible. The image quality is homogenous over the whole sensor width, because the telecentric approach produces no distortion towards the image borders like standard optical lenses do.
