color camera

We received a request from a nearby user to inspect gold plating on SUS with a 10 mm field of view. This is a level of inspection that is difficult to see even with a microscope unless you are familiar with it.
We started with a monochrome camera and blue lighting, and after about two months of trial and error, we finally put a color camera into stable operation.
The user reported, "After about four days of operation, one defective piece was found among the OK products, and all the NG products had some kind of defect. The report said, "Although the problem still remains, the color camera is still valid.
Although there are still problems, we have found an effective way to use the color camera. We hope to promote standardization in the future.
