Welcome to the PF.

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!
