Glass Mountain Optics manufactures glass collimating mirrors for use in large aperture energy collection arrays. GMO's precision collimating mirrors and specially engineered optical coatings offer performance superior to that of other glass alternatives, electroformed mirrors or reproduced acrylic mirrors. GMO can fabricate mirrors using a variety of substrates depending on environmental constraints. Extensive experience and innovations in our production process allow GMO to produce concentrator array segments on thin substrates, allowing for decreased weight without compromising optical performance.

Proprietary techniques developed for the fabrication of lightweight flight simulation mirrors have been refined to allow for the long focal lengths used in collection arrays. GMO has developed in-process and final testing methods to yield near 100% energy return for each segment produced. Process controls allow for matched arrays that significantly decrease set-up and alignment time in the field. GMO offers its experience and expertise in developing lightweight mirror holder arrangements to further speed alignment of multi-segment arrays.
