I don't wish to know. We are not amused. Kindly leave the room!

By the way, did you get my email?

Ask Joy if she will grind me two flats on a 4 inch lens that I have?

A hololens will work fine at the design wavelength and geometry, so it will focus a point perfectly to another point. Problem is, as soon as you have an extended object, the points are away from there, and very quickly you will get distortions and aberrations. These are much more evident than in refractive systems.
