The Colosseum cinema turns its dome into a spectacle of light and color

To take the images beyond the traditional screen, they have been installed 16 Optoma ProScene ZU850 equipment, around the base of the dome, and have been mounted in such a way that they direct the projection towards the upper part of the room, covering the entire dome.

built in 1921, he cine Colosseum Oslo is the largest in Norway and since its recent renovation it is also the first to incorporate projectors to offer a spectacle of light and color on the ceiling.

The building has a large spherical dome 32 meters high by 45 meters wide that is used inside the room 1 to become a large screen where the audiovisual show is exhibited.

A total of 16 Projectors provide an innovative cinema experience that takes images beyond the traditional screen, that in this space is 22 meters wide, allowing you to see them throughout the dome. Bright and reliable equipment was required for implementation., and that they required minimal maintenance since they had to be installed in an area that was difficult to access., around the base of the dome.

The production company, Nordisk Film Shortcut was tasked with finding the right projection solution for this ambitious project. He approached Optoma, who brought in his ProDesign team to advise which pieces of equipment would be appropriate and calculate how many would be needed to combine and cover the entire dome.

The result was the installation of sixteen ProScene ZU850 devices with BX-CTA03 lenses. This is a phosphor laser projector. 8.200 lumens with WUXGA resolution (1.920×1.200) and a contrast ratio 2.000.000:1, incorporating multicolor laser technology (MCL) to deliver high color performance and provide stunning, life-like images with great detail. It also has the DuraCore laser light source that allows it to maintain optimal brightness consistency..

It requires minimal maintenance as its optical motors are watertight and have been independently certified as IP6X and designed for 24 continuous operation.×7.

Offers flexible installation with HDBaseT, four corner geometric fit, portrait and 360° orientations and five lens options offering a throw distance of 0,81 a 35.5 metros. It also incorporates one hundred adjustable brightness settings to help installers match brightness when blending edges with multiple rigs..

The company Vioso has been responsible for creating the contents, for which she has mixed and distorted the images of the 16 projectors to turn them into a sequence and light and color. Three small IP cameras were mounted along with the projectors to be able to align the projected images more accurately..

With Wings Vioso media server solution, Content syncs with the theater's main auditorium projector to create a dynamic experience where content moves across the screen and up into the dome. In addition, Vioso used fiber optics to transmit signals to the projectors due to long cable runs and to avoid delays..

Other items that have been renovated in this room include a new projection screen 22 meters wide. This is a 15% bigger than a tennis court and the largest Ultimate screen in Europe. The screen material reflects the 75% of ambient light to improve images, especially in 3D.

The theater's sound system was also upgraded with 50 new speakers and their 888 new seats, Two rows are electric seats that can be adjusted with the push of a button and have USB charging points for mobile phones.
