Own a piece of histor!!! , these components were sent to space by NASA in the Dartfire missions to observe fires and flame propagation in zero g outer space
These actual pieces were in space!
There is a full paper from Nassau on the whole project. I acquired these pieces a long time ago. They are authenticated, and actually have been to earths outer orbit. The one unit with all the lenses are clearly specified in the documents from Nassau, and they are custom-made, and extremely extremely rare in the thermal imaging world, the other unit is a infra metrics Sterling engine/detector that cools that detector down to extremely low temperatures for thermal imaging
It is actually in still working condition. I had this unit in one of the actual cameras that went to outer space I pulled this one out. I was doing some repairs on a other camera. It’s still in working condition if anybody knows about these types of things it’s a extremely extremely rare fine. The lenses themselves are one in 1 million and very unique, there is papers that can be downloaded online I included some snapshots of them of all of the values, the project and everything that NASA did with these pieces of spaceborne history
