Product Overview

The Digitarium® Theta model is a digital planetarium system designed for use in portable domes.
The new Digitarium Theta is our highest resolution portable planetarium system, designed to be easy to transport, set up, and teach with. It projects high contrast 2160 pixel diameter imagery over a full dome with no blind spots or cut-outs. It is the culmination of years of development effort, with our own innovative proprietary lens design.
The Digitarium Theta uses a laser-phosphor projector with an incredible expected lifetime of 20,000 hours.
The Digitarium Theta also offers quick set up, intuitive user interfaces, excellent projection quality, and a wealth of other features. Digitalis sells inflatable domes in several diameters for a complete portable solution.
