Imaging involves complex interactions between the material and surface characteristics of the test object, optics, lighting and, last but not least, the camera used.
Here, the image is captured by the sensor, processed and then digitised. The required accuracy and speed of testing, as well as the application's requirements in terms of the image sensor, combine to determine the choice of camera.
The choice of camera is generally determined by the testing task. The characteristics to be captured must be represented properly so that the software can analyse them. But what does this actually mean?
Systems in the PV series and all systems with Vision Q.400 can be used with a large variety of different cameras. All standard cameras in our product range are fully integrated into our image processing software Vision Q.400, and have naturally been tested too: Connect, configure and you're done.
Our standard cameras are matrix cameras, all of which are furnished with a monochrome or colour sensor. They feature resolution of up to 5MP and are available with both Camera Link® and Gigabit Ethernet interface.
If you have special needs or requests, please get in touch!
In addition to cameras with matrix sensors, Vision Q.400 also supports line scan cameras or what are referred to as image contact sensors. Line scan cameras are used to test continuous products and in cases where the testing tasks require extremely high resolutions, such as when performing surface inspections or when testing textile tracks. Vision Q.400 is able to process images of up to 500 MB. The Q.400XD system can be used to split extremely large flows of information from a single line scan camera across multiple controllers in a synchronised manner.
One special feature is what are referred to as image contact sensors. In these, the lighting and the image sensor are precisely harmonised with each other. This offers a major benefit in that the time-consuming and often sensitive alignment between camera and lighting can be dispensed with.
GigE cameras The image processing software Vision Q.400 supports multiple Gigabit Ethernet cameras with a wide range of sensor sizes by different manufacturers such as Baumer, BASLER, Allied Vision, Technologies, MATRIX VISION, JAI, Sony, NET, SVS-VISTEK or Point Grey Research. Vision Q.400 can handle all the parameters required for the GigE Vision standard.* The user interface offers straightforward access to these parameters.
* All other parameters can naturally be accessed using an appropriate script.
So how does one choose a suitable camera?
The best way is to ask yourself the following questions:
Using a camera with a CameraLink offers numerous advantages, but it is also associated with a couple of requirements and drawbacks.

Cameras with a GigE interface offer numerous advantages; in fact, they are ideal for two quite typical applications.
Typical use cases
The external conditions for efficient testing procedures are often far from ideal. Sterile laboratory-type conditions only prevail in the rarest of cases. On the contrary, quite frequently it is necessary to deliver excellent results under adverse conditions. Our camera systems are ideally designed to handle such conditions. Combined with a robust enclosure, our systems satisfy protection class IP67 (International Protection). This provides you with a guarantee that our cameras will function perfectly under the harshest of conditions. Oily, dusty or metallic air? No problem. Unaffected by adverse mechanical conditions and delivered dust- and splash-proof to boot, Q.VITEC systems deliver maximum performance under all conditions.
