That doesn't look like a lens - it looks like a temporary protective cover.
But without seeing or knowing the context, it's hard to give a good answer.
It slip in here. From what I saw a IR filter is pink. This is clear. When buy new one it has tape on it. So maybe this just a way of sealing it before it install

Ok, it's just a dust cover to keep the IR cut clean until installation.
Thanks for info. When I clean other camera I will remove them.

Dust cover? Maybe.
It might be added to lower the friction when the IR cut filter physically moves in or out.
It might be a spacer, so the elements in the optical path are in the right location.
Your 2nd pic sure looks like a part of the IR cut filter. This moves a glass piece (with IR coating) into the optical path.
Good luck,
