Provided are pharmaceutical compositions comprising at least one vitamin D-containing compound, at least one corticosteroid compound, and at least one solvent component selected from the group consisting of triglycerides, sorbitan, sorbitan fatty esters, cetearyl glucoside, PEG-n sorbitan stearate, acrylamidesodium acryloyldimethyl taurate copolymers, and mixtures thereof. A compact and low-power laser light image can thereby be formed and seen by an observer from outside the properly constructed three-dimensional projection surface. The method assesses a cost of at least one via proportionately to a cost that the via introduces in the design of the integrated circuit. A corresponding production method is disclosed in addition to the microfluid system.
