Don,
... and anyone else... dig out a copy of his patent on his microscope, Rife that is...
There are more pictures of the incomplete instrument on line, but I poked around a few years back and found a picture of the complete unit.
As I said it is unclear to me that it achieves its stated objective, to see below the Fraunhauer limit using light in the optical spectrum. You're generally limited in terms of size of the object you can see/magnification by the relationship related to wavelength and constructive/destructive interference. His microscope design claims to circumvent the destructive interference that normally sets the limit.
Being not sophisticated in optics and light physics I can't tell by inspection if his claim has any merit at all - but from what little I know, it does seem doubtful.

He might have got greater resolution using blue light right at the fringe of visibility and ultraviolet. Like the laser discs that use blue lasers instead of the traditional red to allow for more data storage in a given amount of space.
But then maybe he used oxygen-free quartz lenses in his optics to give more tessitura to the magnified images.
