[Ed...] Posted May 7 Share Posted May 7 Hello, I am tasked with measuring the width of a couple of channels in a thin steel plate. These channels do not have sharp edges, but rather, due to the nature of the manufacturing process, the edges are somewhat rounded off. How would one go about measuring this with a Zeiss O-Inspect optical sesnor? I've tried setting manual points, but consider that inaccurate. Picking up a line gives me a lot of false positives that are hard to filter out for. For reference; we're looking at a channel of 3.5 with a tolerance of two tenth (mm) Any tips or guidance would be most appreciated. W. Link to comment Share on other sites More sharing options...
[Cl...] Posted May 7 Share Posted May 7 Does your O-inspect have a DotScan (White-light). I think that might be the best option depending on how steep the angle is on the channel walls. 1 Link to comment Share on other sites More sharing options...

Haha, must have been at least 15 years since I last used something like that! 😄 Reprorubber seemingly doesn't exist in Germany - we used a liquid 2K stuff called Technovit 3040, which cures to a hard yellow mass with minimum shrinkage. Frankly, I don't know of a reliable method to measure a channel like this with the camera. Working with plastic parts, I often have similar parts. In the pic above I wouldn't even trust my own eyes to spot the correct "edge" of the channel. So your only option seems to be a manual measurment (crosshair or stencils).

[Ri...] Posted May 7 Share Posted May 7 There are a few things I might suggest: Zoom out (what zoom are you currently on?) Have you tried the Glare Filter? Have you tried using directional lighting? 1 Link to comment Share on other sites More sharing options...
[Cl...] Posted May 7 Share Posted May 7 Unrelated, but I've been to Germany twice. Frankfurt, Kaiserslautern, Munich, Karlsruhe, Koenigsbach-Stein, Bretten. Beautiful country. 3 Link to comment Share on other sites More sharing options...

Hehe, unfortunately that's not an option either. Please sign in to view this quote. Hi, thank you for your reply. I have tried 0.5 and max zoom, but that is of no help to be honest. Is the glare-filter an option to buy? We don't seem to have it/cannot find it. 3 We have adjusted the lightning all sorts of ways, as to emphasise the channel shadow, but this doesn't seem to be enough. I'm thinking to put a light next to the table, to be honest. But that's something to try on the next batch. Thanks for the help.

The glare filter is quite new. I think it was added in 2024? But I doubt it will improve the situation essentially. 1 Link to comment Share on other sites More sharing options...
