Case or Lens Cover

Let me start by saying how excellent this camera is. I used to struggle with the Intel depth cameras which which turned me away from using depth cameras but this ZED camera nothing but ease of use so thank you Sterolabs!

I am using the ZED2i outdoors in a very harsh enviroment. Prone to scratches and high heat.I know the rating is IP66 but thats not enough protection for my application. Is there any recommendation for a outer lens for more protection?
