   Quicker and easier than designing a lens assembly to do the job and (and   
   very likely to give better image quality)  is to use a USB   
   endoscope/bore scope video camera and place the  whole camera  though   
   the hole.  Ebay shows some 10mm diameter cameras with a few meters of   
   USB cable for around $80.  Not sure if it will work with an Ipad.
