For operation of a passive microprojector, an exterior light source such as a transmission graphoscope is urgently needed. On such an exterior light source, a carrying plate (7) of the microprojector is placed on an object glass (15) or exterior housing (14) instead of a transparency. The light emitted from a light source (17) in the graphoscope is intercepted in a condenser lens (13), where the light bundle is gathered to illuminate first the object glass (12) and then the object (11). The light bundle is reproduced into the entrance aperture of an objective (1). The magnified picture is projected onto a projection screen or a white wall. Picture sharpness can be adjusted with the arm (3) and the height of the picture with the movement of mirrors (2) around the axle (10). Za delovanje pasivnega mikro projektorja je nujnopotreben zunanji izvor svetlobe, kot je presevni grafoskop. Na takšen zunanji vir svetlobe položimo nosilno ploščo (7) mikro projektorja na objektno steklo (15) ali zunanje ohišje (14) namesto prosojnice. Svetlobo, ki jo oddaja vir svetlobe (17) v grafoskopu, zberemo s kondenzorsko lečo (13),kjer zberemo svetlobni snop in osvetlimo najprej objektno steklo (12) in nato objekt (11). Svetlobni snop se preslika v vhodno odprtino objektiva (1). Sliko povečano projiciramo na projekcijsko platno ali belo steno. Z ročico (3) nastavljamo ostrino slike, s premikom zrcal (2) okoli osi (10) pa nastavljamo višino slike.
