A method for maximizing light transmission through an optical switch which includes a first mirror to direct a beam of light received from an input optical port to a second mirror that redirects the beam of light to an output optical port, the first and second mirrors each being pivotally actuated in first and second directions. These ink flow paths are constituted by first communication paths, which communicate with the ink outlets of corresponding ink chambers, second communication paths, which communicate with the corresponding ink inlets of the recording head, and convergent flow paths, which connect the first and the second communication paths and converge as they approach the recording head. The rendering unit is configured to receive vertices of a triangle. The aperture-defining lens group includes at least one high-index lens made from a transparent high-index material having a refractive index nHI, where nHI>nSIO2 and where nSIO2 is the refractive index of silicon dioxide at the operating wavelength. Also disclosed are methods for treating, preventing, and diagnosing Alzheimer’s Disease. Suitable solvents in which both fullerenes and PAHs are soluble include o-xylene, toluene, and o-dichlorobenzene.
