"biphotons carry lower energy of longer-wavelength photons while having shorter wavelength higher-energy photons... 400-nm light image thcell and achieve effect of 200-nm light, cells will be unharmed , and resolution of UV... shines laser light into crystal that converts photons passing through into biphotons... mirrors, lenses, and prisms, each biphoton split, shuttled along two paths, 1 paired photons passes through object being imaged... computer builds image of the cell based on signal photon"
