ASK THE EXPERTS
Vision Systems Questions
We’re looking for a solution to photograph bearings and shafts 7 and 3mm dia respectively after applying grease or adhesive during automated manufacturing. Photographs are close-ups (macros) and require focus stacking. Results are stored for later use in order to diagnose end of line tester and others.

Hi Michael, we use a tool in MIL Registration for separate extended depth of field and depth-from-focus to produce, respectively, a single all-in-focus image and an index image from a series of images of a motionless scene taken at different focus points. The index image can subsequently be used to infer depth.
I would like to answer your question, but I don't understand it completely, would it be possible, that you describe the task in more detail? Maybe you have a picture of what you looking at.
Hi Michael, Not sure how fast you need to acquire these images but we have lots of tools to help accomplish deep focal length images from macro closeups of objects. Please contact me and so we can get more info and provide more answers.

Dear Michael Grunberg, I think we can use CCD with telecentric lens to satisfy your requests. For example, 1/1.8 inch CCD, along with 1x lens to get 7mm view; 1/3 inch CCD along with 2x lens. Please let me know if it's clear to you? You can also visit our website www.mvotemoptics.com for more information. Thanks, Terry.
Hi Michael, CCS has a solution for focus stacking that is open architecture and works with most cameras and vision systems. It is part of our Computational Imaging software (SDK) and can extend depth of field by a substantial amount. The parts can be stationary or in motion. More information is available at http://www.computationalimaging.com/applications/extended-depth-of-field.aspx. Please feel free to contact me at 781-460-3665 with any questions.
