What exactly are you looking for? Do you have example images of your application and a more detailled description of the task? Like reading the wafer ID`s (OCR) or verifying (OCV) in an ONLINE or OFFLINE mode? Is there a specific wish forthe interface? Greetings

It seems for my like just - using the HE1600T Smart Camera(or PC-Basedfor fast applications) and - use the OCR Trainable Font Tool/OCV Tool and -improve the contrast abit (maybe DOAL or Darkfield) Note: currently only 10-15 Greyvalues contrast! => and the result could look like attached...

In fact, our customer is using Cognex 1721 in the machine, and they did evaluation with several similar products few months ago but eventually, they chosen this one. No matter what kind of wafer comes in, it exactly identify it well so even it's one of the most highest cost of the BOM they still don't want to replace unless someone could prove that solution could do something but with lower price. As I knew, one of the most important advantage of 1721 is it combined with lighting so it is able to adjust its lighting automaticallyaccording to the target. I agree with you about contrast is quite close to decrease possibility to identify the ID correctly.
