SA Photonics is as mysterious as eMagin. Why hasn't anyone bought them? State-of-the-Art, expensive but deep pockets could drive down the cost. Anyway it looks like they are upgrading their site perhaps recognizing new found interest. Only eMagin displays are used. Is anyone seeing a Unity in Design? In my mind the first iteration of the current notion of how a AR Headset looks and operates started with SAPs AITT developed for the USMC.
