Morphology

ultrapure = pure (transparent) = ultra + pure

The meaning is directly compositional: 'ultra-' intensifies 'pure' to mean extremely pure.

Etymology

Ultrapure combines the part ultra-, which means 'beyond' or 'extreme' (as in ultraviolet), with pure, which means 'clean' or 'without impurities'. So ultrapure means 'extremely clean' or having almost nothing wrong or mixed in.
