new spin on telescope design

Interesting.. So instead of becoming longer, it's becoming wider :bsmilie:

Pretty interesting...

but it's fixed aperture and the end result seems pretty small.. only for tiny sensors

Folded optics is not new. Just that this time, it can be folded multiple times because of advances in ray tracing software.

yup they said it was an updated approach to folded optics.
well they're still at the prototype stage, grinding away at their salt crystal

Probably will have fixed aperture as in a mirror lens. Also, bright spots will be rendered as donuts when our of focus?
