This type of planetarium uses a mechanical device, such as fiber optics or light luminous lamps, which projects towards the dome stars and other astronomical objects. Until the end of the past century they were the only type of planetarium available.
Today this type of planetarium has reached a high-level of quality and Konica Minolta is one of the best manufactures in the world.
Current state-of-the-art optical planetarium technology is represented by the Konica Minolta Infinium Series. This series has actually two models: the Infinium S, for domes in the range from 12 to 20 meters, and Infinium L, for domes in the range from 18 to 27 meters. Both models offer fiber optics projection in conjunction with metal halide lamps for high quality projection in a compact body.]]>
This is the most complex but also the most powerful type of planetarium available today.
Konica Minolta was the first company in the world to develop the optical-digital hybrid. Now, with GEMINISTAR III, Konica Minolta combines the best optical planetarium available – the Infinium series – with different types of digital systems, such as the Super Mediaglobe II.
GEMINISTAR III is a true wonder of Konica Minolta experience in planetarium technology. This hybrid planetarium reached a so high level of perfection that it is possible to acquire a pair of binoculars to watch projected globular clusters and nebulae. They will appear like under a real sky!]]>
The Infinium L is an optical type of planetarium that projects the beautifully realistic starry sky, featuring the brightest, sharpest, and naturally twinkling stars.
The Infinium L is the new generation model of Infinium series of optical planetariums. Konica Minolta Planetarium puts all of its precise know-how in opto-mechatronics into reproducing world’s most realistic star field. Interviewing planetarium professionals about their way of planetarium operation to develop the easiest control console to provide high level planetarium presentation.
By using latest astronomical data and our unique laser processing technique. Star Plates, core parts of fixed star projector, has manufactured by using our original precise laser processor. Latest astronomical data and precise calculation for compensation of lens distortion provide superb accurate star positioning. Accuracy of projected position of each fixed star in less than 0.5 arc minutes. Audience who watches the star field by pair of binoculars will be able to study that the Milky Way, Andromeda Galaxy and major deep sky objects are composed by tiny stars as same as real sky.
We have been putting concentrate on making most realistic star field. We took the Pogson’s law as the basic concept then made modification on the faint stars to reproduce more natural appearance. Hybrid Optical Fiber system prevent any uneven illumination in the entire star field. Therefore the star magnitude is accurate for the entire sky.
We chose Metal Halide Lamp as the light source. Metal Halide Lamp has 6000K color temperature and it is similar to the Sun. Fixed stars brighter than 2.5 magnitudes have each color as natural by using filters on the star plates. These colors do not affect reproduction of magnitude.
Fixed Star Projector has Digitally Controlled Shutter. This mechanism enables the operator to switch the horizon as tilted or horizontal. Tilted horizon is used for space travel show. Horizontal horizon is used for astronomy education.
All fixed stars have scintillation function. They randomly twinkle as natural.
Sun, Moon and Planets projectors also have Optical Fiber System. The projected images are much brighter than other former system. Not only planets but also major satellites such as Phobos, Deimos, Io and Europa can be projected without any additional software. Accuracy of each planet position on calculation is less than 0.2 degree within plus or minus 3,000 years.
Adopting universal design and newly designed GUI made the best function possible remarkably for operation. Regardless of the age of operator, young or old, the console can easily be used in the dark room with dim light because of easily usable layout, and larger letter and pictograph are on it. Also, it utilizes Windows with newly designed GUI (Graphical User Interface), and made the easy operation possible remarkably for operators.
The operation of all peripheral equipments can be done from Console by the network control. Needless to say, during Automatic operation, Manual or Semi-Automatic operation, All-sky digital projection system and sound system can be controlled with perfect freedom.

The Infinium S reproduces realistic starry-sky with which audience feel temptation of observing the show forever, pursuing beauty and reality and high performance of learning astronomy.
The Infinium S is the new generation model of Infinium series of optical planetariums. Konica Minolta Planetarium put all of his precise know-how in opto-mechatronics into reproducing world’s most realistic star field. Also they investigated planetarium professionals about their way of planetarium operation to develop the easiest control console to provide high level planetarium presentation.
Infinium S reproduces the brilliant, sharp and realistic starry sky, by adopting the technology of optical fiber and high luminous lamp.
This optical planetarium introduces the projection method of light through the optical fiber with lens, and metal halide lamp of high color temperature. It can project natural-like and realistic starry sky, reproducing in high fidelity the difference of brightness for fixed stars and particular color tone of them. Also, in spite of a compact star-ball (approx. 70cm in diameter), it makes substantially increasing possible number of bright stars.
Since announcing the GEMINISTAR , the world’s first integrated planetarium, in 1994, Konica Minolta has been a consistent pioneer of integrated systems, sending many integrated planetariums out into the world. And today, as a result of further research and development, a new model is born: GEMINISTAR III, the integrated planetarium of 3rd generation.
GEMINISTAR III completely centralizes optical and digital systems into a single system. The integrated console realizes a broad range of programs and effects in real time through seamless operability which makes no distinction between optical and digital.
Furthermore, through organic fusion of a real, beautifully starry sky, and powerful Computer Graphic (CG) imagery, it is possible to project the dramatic, immense spectacle of the universe on the full dome screen.
|Dome Type||Horizontal / tilted|
|Dome size in Diameter||12~20m (Type S)
18~27m (Type L)
|Number of seats||100~200 seats (Type S)
200~350 seats (Type L)
|Recommendable Number of Fixed Stars||12,800 ~ 15,000 pcs. (Type S)

GEMINISTAR III utilizes the world’s first hybrid optical-fiber method for the fixed-star projection system. By enhancing the efficiency of utilizing light, not only the bright fixed-star can be projected with less power consumption, but the bright stars can be reproduced as if the audience is in the real star-field with the small and brilliant star images which are made by the direct projection from the ending surface of the optical fiber. It features an efficient metal halide light source with high color temperature producing the natural colors of stars more expressively with high fidelity.
GEMINISTAR III reproduces not only beautiful star-field that attracts and relaxes audience, but also dynamic projection image beyond time and space of three dimensional universe that could never be realized by conventional types of planetarium.
GEMINISTAR III has evolved the way of operation a great deal. Without awareness of the difference between an optical planetarium and a digital planetarium, the intuitive operation can be done freely in real time. The integrated console panel has well designed layout with larger size of lettering, pictograph letter etc. on it adopting the universal design totally for easy operation. Also, newly designed GUI (Graphical User Interface) has made the operation remarkably in higher grade.
