Digitarium Digitarium Alpha 2 lens remote control
Maximum Dome Diameter
Approximately 33 feet/10 meters. Brightness is the main issue, since the larger the dome, the larger the surface area the light from the projector must cover.
Resolution
768 pixels across a diameter
Field of view
180 degrees, full sky.
Pixels per degree of sky
4.3 average
Angle of Projection
175 degrees
Base Projector Brightness
4000 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. Please contact us if you may be interested in a brighter system.)
Contrast Ratio
Approximately 900:1
Lamp life
3000 hours
The projector has two lamps which can be used one at a time, or both together for the brightest projection.
Image Quality
Some violet color separation is present, however we do not believe that this will distract from your teaching. This is a tradeoff in the interest of an affordable system and has been improved from the previous model.
