Why would a camera manufacturer need our ARGOS matrix 200?
Have you ever been annoyed that you take photos and there a UFO hovering in the picture, always at the same spot? Most likely, this is not a UFO, but a dust particle. If it’s on the lens, it’s relatively easy to fix. Inside the camera, however, it becomes much more complicated.
Dust particles on camera sensor and IR cut filter
This is not only annoying for the camera manufacturer – it simply cannot happen. Period. It is essential that no dust particles are deposited during camera assembly despite the cleanroom conditions. This applies in particular to the sensor and the IR cut filter, which filters out infrared light and protects the sensor.
This is where it gets tricky. Strictly speaking, three surfaces must be dust-free: the surface of the sensor and the front and back of the infrared filter. And, of course, no particles or fluff must be overlooked, which could then be caught between the filter and the sensor and no longer be removed. With conventional visual inspection by the human eye, it is not always possible to identify which of the three surfaces contains dust particles. To be on the safe side, all three surfaces would have to be cleaned before installation. This is a considerable effort.
ARGOS matrix 200 inspects during production
This is where ARGOS matrix 200 shows its strengths: On the one hand, the surface inspection system detects which of the surfaces has dust on it. In addition, the system measures how large the dust particles are; algorithms decide whether particles are relevant or irrelevant in terms of limiting the imaging quality.
“All of this happens during production. And not in random samples, but for every single camera. The manufacturer can afford this and save money in the long term. Because the increase in product quality benefits both: the customer through reliable freedom from defects and the manufacturer through reduced expensive rejects of finished cameras. And the manufacturer can rely one hundred percent on the test results of the now two ARGOS matrix 200s,” explains Sales Manager Dr. Roland Goschke.
