We started climbing from 34000 feet to 36000 feet; working our way around thunderstorms. We got a strong acid smell and haze in cockpit. The First Officer was [the] Pilot Flying. We put on Oxygen Masks and established communication. I instructed the First Officer to fly the aircraft. I would talk to ATC and work the situation. I saw ZZZ on my screen and to the west; the weather was clear. I typed in direct ZZZ. I asked ATC what runway was in use. I pulled up the runway Final Approach Fix. We flew maximum forward speed until a few miles from the Final Approach Fix; coupled ILS auto land; flaps 25; [and] maximum auto brakes landing.
