Tempest Enclosure

EOS designs and manufactures high-quality telescopes with exceptional technical performance for imaging, tracking and laser beam delivery.

We are experts in designing, installing, commissioning, operating and maintaining best-in-class observatories. This allows us to offer unique solutions that meet the most challenging customer demands.

The Tempest Enclosure is optimised in design for beam directors, and optical communications and is ideal for astronomy applications. It incorporates a composite glass-reinforced plastic (GRP) rotating dome with vertical (up-and-over) bi-parting shutters.

The pre-assembled modular dome and ringwall kit minimises on-site construction and integration time. This proven design also reduces ongoing maintenance costs, making it an economical system to run.
