Product Overview

Digitarium Theta

The Digitarium® Theta+ model is a digital planetarium system designed for use in portable or fixed 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.

Choose from a lower cost Basic option or much more powerful Professional software package. See specifications below for details.
