Digitarium Gamma Portable Digital Planetarium System
The Digitarium Gamma Portable model is a digital planetarium system designed for
use in portable domes. It is very similar to the
Digitarium Alpha 2+ Portable model,
but offers higher resolution (about 87% more pixels) and a
slightly brighter projector. It has the same unmatched usability of other
Digitarium systems with our exclusive backlit, handheld
remote control.
This model is designed for those who want relatively high resolution, the best projection
quality in a portable Digitarium system, and highly immersive projection
(175 degree projection angle).
If you intend to show a lot of fulldome video shows,
immersive environments, or scientific visualizations, the higher resolution will be invaluable.
Starfields will also look better, especially with the enhanced contrast and our high
quality proprietary lens.
Despite all these features, the price is a fraction of other high quality full dome
fisheye planetarium systems of similar resolutions and brightness!

Maximum Dome Diameter
|
Around 54 feet/16.5m. Brightness
is the main
issue, since the larger the dome,
the larger the surface area the light from the projector must cover.
|
Resolution
|
1050 pixels across a diameter
|
Field of view
|
180 degrees, full sky.
|
Pixels per degree of sky
|
5.8 average
|
Angle of Projection
|
175 degrees
|
Base Projector Brightness
|
6100 Lumens with non-fisheye lens (Provided for comparison purposes with other systems. Actual brightness with a fisheye lens is significantly less due to not projecting the whole video rectangle and differing lens properties.)
|
Contrast Ratio
|
The minimum contrast ratio with both lamps is approximately 2100:1.
|
Lamp life
|
Up to 2000 hours on high
The projector has two lamps which can be used one at a time, or both together for the brightest projection.
|

Digitarium Gamma systems use our most advanced
proprietary lens design for the best projection quality available in a Digitarium system.
