Posted 15 Mar 2017 Different color lighting may help (ex: red or blue.) You may also try a polarizing filter if you aren't currently using one. This can help with glare issues. I'm not sure what lighting system you're currently using, but you may also need to consider a dome light, diffused light, etc. At a past employer, we were having a lot of issues with vision on a new machine, and we were able to get Keyence to come in with a selection of lighting and filters and spend a day working with us on proper lighting selection and fine-tuning configuration.

Posted 21 Mar 2017 Can you post images with notations on them that show what you are inspecting? A good/pass image and a bad/fail image would also be helpful. From there, we can look at the images to help solve your problem. At my facility, we have solved a lot of our lighting issues by using infrared lighting and filters. This way, ambient light conditions have little to no effect on the process (unless you are directly under a window where the sun rises or sets). Share this post Link to post Share on other sites
