Camera+Lens

[userftf]

Hello!

I'm looking for a camera with an appropriate lens which could give a full screen image of the distance between the anode and cathode, which varies between 1 micrometer - 1 millimeter (see the experimental setup attached). Minimal distance between the object and camera is about 55 mm. What would you recommend?

Thank you!

In what way is this related to digital I/O?

Maybe machine vision would be a better place?

If so, please ask the moderator to move your post.
