I think you found the lenses too early; if you get the mission that early and proceed to complete it right away you'll never get Gale's letter. This has happened to me as well.

If you really want to get the letter you can wait until receiving it even if the mission has triggered, just don't complete it. The mission has no time limit so you should be fine. Simply avoid entering the Research Center with two lenses in your inventory (entering Research Center without lenses is ok).
