A Theodyne prism is the primary catalyst for realistics reactions. It is the only known way to induce a controlled realistics reaction, and the primary invention enabling interstellar spaceflight by way of changing the constants of reality. Theodyne prisms are synthesised from raw Theorium crystals. The exact specifications of Theorium prisms are trade secrets of Theotech.
The fabrication of Theodyne prisms involves a multistep process, beginning with the purification of Theorium. The purification process eliminates impurities that could otherwise interfere with the prism's function, employing methods such as high-frequency sonic vibrations and phase separation techniques.
Following purification, the Molecular Stabilisation stage enhances the element's inherent stability. This process prepares Theorium for the subsequent precision shaping phase, wherein the material is sculpted into prisms without making physical contact, typically through levitational sculpting techniques. This method prevents the introduction of imperfections that could compromise the efficiency and reliability of the prism. At this point, the prism has assumed the iconic shape of an atomically perfect sphere of a radius of 22 centimetres.
Reality Alignment Calibration is a critical phase in the fabrication process, necessitating the application of directed energy pulses to adjust the prism's realistics properties accurately. To achieve perfect "baseline condition", meaning to have the prism emit a field of baseline reality (R=1) when imparted with a neutral beam, an annealing process has to be performed under close to absolute darkness. Supercooled "darkness chambers" are used for this process - they are completely devoid of light and blackbody emission is minimal due to the low temperature inside the chamber.
Once assembled correctly, the prism is placed in an optically transparent resin cube so pure that it is nearly invisible. The prism can then be used in reality alteration circuits.
