One downside perhaps is the fact that the mirror surface is prone to scratching, so it is a toy to play for few weeks.
so separation of the two poles is focal length of each mirror ie R/2
There is NO hologram: nothing is recorded/reconstructed, and there is no need for coherent (laser) light! Some adverts put in "hologram" - just a gimmick!
The observational value is high: just note how the image is real (can be cast onto paper) and has the correct chirality (ie no change of handedness) but is rotated 180 deg about the common axis of the mirrors
cf simple optical bench set-up with a convex lens, with real object/real image
There are internet sites explaining the optics, with good ray diagrams ( as of old!)
Small objects placed in the device appear to float above the surface
Great fun watching people trying to grab an object that isn't there
One star lost because the parabolic mirrors are difficult to clean without damaging them and spoiling the effect
Be warned that the item is smaller than normal 6 inch standard ones. This is only 4" in diameter.
