Product Description

Inflatable Education Projection Classroom Planetarium Show Dome Tent

Usually ring raised domes are heavier and therefore not as portable as the standard dome, but find many applications where a dome is set up for more than one day or even as a temporary theater in museums or other public spaces such as malls, lobbies, and common areas.  Ring domes have been made in sizes ranging from 4-meter domes fitting in trade shows or classrooms with tall ceilings to 8-meter portable theaters.


Our dome sizes ranging from 3 to 10 meters in diameter. And they can be made with rings and without rings.The rings are inflated by the same fan that inflates the dome. Each ring has a diameter of 30 cm (1 foot) and up to 5 tubes can be provided for the spring line desired by the customer. One or two tubes hold the dome diameter and adds to stability. Three to five tubes provide a wall against which chairs can be placed. Customers wanting a dome structure with chairs often choose the ring dome.All 4 and 5 meter Domes come with the standard 6 foot door. All others come with the new 7 foot door unless otherwise specified.


SEATING CAPACITY FOR RAISED DOMES

(non-raised dome capacities are smaller, due to the projection surface reaching the floor and audience members obstructing each others view)

Grey squares represent small folding chairs. Ground seating will allow for greater capacity (depending on the age of the group).
LEFT: unidirectional configuration with a spherical mirror (ideal for both fulldome films and night sky)
RIGHT: concentric configuration with a fisheye projector (ideal only for night sky)


The illustrations above represent round and theater seating for 4 to 9 meter Domes.

The grey squares are the size of standard folding chairs that can be reasonably placed for safe operations. Of course if ground seating is preferred, the the capacity will change depending on the age of the group.. Generally speaking floor seating will allow for more people to be seated than chairs.   
A simple way of calculating capacity for yourself is to draw a circle the diameter of the dome you intend to buy and sit some representative people inside your circle and do a head count.
