The Cosmo Leap Sigma is an optical projector for mid-size, municipal planetariums operated primarily for educational purposes. It is designed to benefit all planetarium users, especially children who learn and grow through astronomy. Combining both star and planet projection, it is the smallest projector in its class worldwide, offering 80 constellation images, reference marks and more to enable a full, all-inclusive analysis of the night sky in the limited space of a mid-size planetarium dome.

Quiet operation on par with that of library noise levels enables novel show types, such as projection accompanied by musical concerts. The unit's pitch-black colour, which blends into the dark, and elaborate, polyhedral, light-emitting projection foster an elegant harmony as they recreate the starry sky. Homes and schools cannot easily show children the stars because they would have to take them out at night and need telescopes. Thus, medium-sized planetarium domes operated by municipalities are used for education all over the world.

However, the space in their domes is limited and used to be occupied by multiple projectors providing an accurate, educational narrative of the sky. The Cosmo Leap Sigma is exceptionally compact, but integrates these projectors and prevents them from blocking the beams of light. In addition, a quiet direct drive motor is used for the diurnal axis, which allows a better appreciation of the starry skies, achieved by ultra bright LEDs with low power consumption, and enables new audio-based dome experiences such as concerts and healing programs.

A rigid arch shape is used for the main frame, and the planet projectors are combined systematically on a precise straight line, producing an aesthetically streamlined and elegant silhouette. The extra space made available in the dome can be flexibly designed for appreciating the projected stars.

All the projector movements of the Cosmo Leap Sigma convey the orderly universe. The jet-black star ball is surrounded by a rod framework of elaborate polyhedra. The rods extend radially from a myriad of lenses and are anodized in black to make the jet-black star ball glitter like twinkling stars. The elaborate design harmonizes with the cosmic space in a dome, inviting children to enjoy detailed stories of the starry skies.

The Cosmo Leap Sigma uses only high brightness LEDs as light sources, eliminating the need to replace lamps and protection fuses. Daily maintenance requires only cleaning of the air intake filters and exterior surfaces, contributing to improved work efficiency. The reduced maintenance time helps planetarium staff concentrate on narrating and running programs, resulting in an improved experience for the audience.
