The question has already been answered but for completeness sake: unlike the regular lenses from bounty rewards (Madurai Lens, Naramon Lens, Unairu Lens, Vazarin Lens and Zenurik Lens) the "Eidolon Lens" is a blueprint. What you need is a Greater Lens blueprint from the market. The "Greater xxx Lens" blueprint costs 200k credits or 40 plat and the finished lens is an ingredient for the "Eidolon Lens" blueprint. Once you crafted one of these, the result gains a name like "Eidolon Zenurik Lens" which you can then equip on a warframe or weapon.
