This week I sat down again with Ilya, the Dark Lord of Optics, to answer some lingering questions I've got about prism optics. I wanted to understand how they work relative to traditional rifle scopes, and some of the tradeoffs required when designing them. During the conversation, we also wandered over how rifle scopes work in general, reticle color selection, durability, engineering tradeoffs, and more. I'm also posting the audio-only version of this as well.
