We have a lens that has diameter 30mm, focal legnth 20mm and groove pitch 0.1mm.
Also have a lens that has diameter 140mm, focal legnth 50mm and groove pitch 0.3mm.
 
To stack 2 lens each other seems possible, but not sure.

i'm looking for a lens type that can be used for Virtual reality.
The requirements are; small Focal length, with minimum lens distortion and a small groove pitch. 

You might have seen this project; http://www.roadtovr.com/2013/08/14/infiniteye-210-degree-hmd-prototype-contest-vote-7508 

Could you advise a lens type for this application? Something in the range of 40/50 mm focal lengt | 5x/6x zoom| Pitch of .1 mm. It would also be possible to stack 2 lenses on top of each other of course.
