It won't mean much to you, so we have also given them a christian name. The segment referred to here is ADERNO, which is a tree.

It is an immense structure over 20 metres high, a meccano® set with parts weighing several tonnes a piece, and it has to be adjusted on the tiniest of scales. Precision is demanded by every telescope in the world, but the bigger the telescope the harder this is. Especially when we are talking in microns. Read this article
