German company to install laser projection system at planetarium | Patna News

PATNA: Work on the modernization of the projection system and the redevelopment of the dome screen and quarter-century-old auditorium of the planetarium of the Indira Gandhi Science Complex, commonly known as Taramandal, is expected to begin soon.
A German manufacturer of optical, mechanical and digital planetarium projectors, Carl Zeiss, is likely to obtain the work order for the installation of a 2D / 3D RGB (red, green, blue) digital laser projection system at the cutting edge technology. with chained hanging dome screen. According to sources, the work order would be delivered to the selected company within a week.
Three foreign companies – one from the United Kingdom, one from France and one from Germany – had participated in the technical and financial offers for the modernization of the planetarium.
The new projection system should be ready within a year and a half with an estimated expenditure of Rs 36 crore. The state government has already released funds to the Department of Science and Technology for the modernization of the planetarium.
The new system with digital aids would improve the viewing experience in multiple ways. A planetarium official said the technological shift from celluloid films to digital 3D stereo projection would produce a unique representation of celestial objects with a visual experience never seen before. “It will be fully digitized with 3D shows as well as 2D. It would be equipped with a hybrid optical system, ”added the manager.
State Minister of Science and Technology Sumit Kumar Singh said earlier that the RGB laser projector would allow exceptional brightness and image intensity and make the viewing experience more vibrant for people. “The latter projection system would suit the dome-shaped planetarium, which has a base diameter of 16 m. In addition, the aluminum screen will also be replaced by a dome-shaped hanging screen, ”he said.
As per the plan, the seating arrangement in the domed gallery will be redesigned according to the new screen and projection system so that viewers can get the right angle to watch the shows. “The number of seats will be reduced to 225 from the existing 261, as more comfortable chairs will be placed, providing roomy space for viewers for 3D and 2D shows,” said the planetarium manager.
A large capacity optical telescope will also be installed in the planetarium. The telescope will be purchased through the National Council of Science Museums at Rs 10 lakh. The telescope will allow students, researchers and civilians to visualize astronomical events, including eclipses (lunar and solar), planetary movements and meteor showers. For this, a separate screen will be set up for sky observers.
