Icestorm II 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 IceStorm II Enclosure is suited to large beam directors, and accommodates apertures up to 2.4 m; this makes it ideal for optical astronomy applications. Its robust dome construction minimises thermal effects, protects against vibration and reduces wind shake.
