    I would like to built a periscope with lenses for a Smartphone. I know that the Smartphone camera has approximatley 4mm of focal depth. I don't want a vignette effect.

    Unfortunatley I do not know how to set the specifications of the lenses. Can someone help me please ??

    I did a Google search on how to build a periscope with mirrors and lenses, and got lots of great hits. One of the first on the hit list is a NASA web page with an Educational tutorial on how to build a periscope:


    Check that page out, and do the Google search to find other hits. Let us know what you find! :smile:
