Next generation planetarium system MEGASTAR-FUSION

The planetarium technology of projecting the starry sky on the dome surface is evolving day by day.
There are optical planetariums such as MEGASTAR series precisely reproducing the starry sky. There are digital planetariums dramatically enriching the content of dome shows. Also, there is hybrid type using both together.
Furthermore, Ohira Tech Ltd. has developed an innovative planetarium system that brings the hybrid system to a new level. It is the next generation planetarium system FUSION (patented).
It literally fuses the optical technology that displays precise starry sky with the unique technology of ultrahigh-speed digital projection, combining earth scenery, celestial bodies on the starry sky in an unprecedented dimension. When you look up you feel how real it looks like. For example, a star sparkling in a narrow gap between buildings of a big city. A mountain or tree silhouette that stays black in the forest with the starry sky backdrop. A passenger airplane ascends from clouds and suddenly a breathtaking starry sky become visible from the window.
We wish you to try the future of starry sky experience drawd by the FUSION .

Ultra precise technology of star plate manufacturing

A star plate can be said to be the heart of MEGASTAR. Our company has a precise processing technology to produce star plates of outstanding quality.
For many years Takayuki Ohira accumulated know-how of star plate manufacturing.
In collaboration with Sony DADC Japan Inc. we developed GIGAMASK– an ultra-precise technology making single holes in a star plate as small as 200 nanometers. This makes a full 1 Billion stars projection possible.
