1984: After a considerable re-development, Minolta launched its model "Infinium", the world's first single-sphere projector. The dumbbell-form was released from its planetary cage, and the projectors for the solar system objects moved to a special platform outside. Thus, the ball could be adjusted easier and faster to its designated position. Zeiss picked up this innovation and adopted it to its latest models since 1987. In 1996, Zeiss improved the imaging quality stars of the sky by using fibre glass for each star. Now, both the star ball and the fibres are the substantial elements of the modern opto-mechanical projector. The most modern large- and middle-sized planetariums in the world deploy it.
