Hi, I'm working on a tool inspection microscope setup that looks at an edge about .3 mm in radius. fps isn't a big deal, but I'd like to have a very clear image of this edge using a usb camera and an appropriate lens setup. Has anyone ever done this kind of thing before?

Evan, A large percentage of us have done this type of thing before. I would encourage you to figure out the following items: - field of view - how large an area do you need to look at? - what is the smallest thing you need to be able to see. For example if you would like to see a 0.3mm radius, and you want to see how smooth that radius is, then would you want to see 10, 20 or 100 pixels around that radius. The camera is digitizing the image, so you have to figure out what you can accept when you zoom in on it. Are you looking for problems on the radius that are 1/10 of the radius for example. Can you move the field of view as you work, just like a microscope? Does the radius have a 3d component to it too? Are you already using a microscope? If so why not just plug in a microscope camera? Are you undertaking automated measurements? Please feel free to drop me an email or give me a call, and I'll try and point you in the right direction. Andy
