But, it is not a full lens. The other side is open. I suppose to receive an other lense. A primary Like a scope ?

I believe that you have an adjustable anamorphic attachment which uses a prism instead of a lens to "stretch" the image, and can be set to anywhere between no stretch ("1x") and standard scope ("2x"). You can screw it onto whatever prime lens you normally use for scope and it should have the same effect when set to 2x.
