To assist developers we list here a list of Schott Suprax low expansion disks we have available for projects. These are predominantly used for reflective surfaces in various formats, plano, spheres, ellipsoids, paraboloids and hyperboloids. In some cases off axis paraboloids can be produced from them. The thickness are as produced from the original disk dimension milled Plano/Plano but it is possible to reduce the thicknesses to individual requirements where required.

Where zero optical expansion is needed as in satellite design and usage, we produce primary and secondary mirrors from Zerodur ceramic. The characteristics of Zerodur are incredible and often essential where significant temperature changes are exhibited and optical stability essential.

Mass Reduction

As can be seen on the image above, pocketed mirror substrates are key in the reduction of mass especially in rocket launch costs and, where Space bound telescopes are involved, a significant reduction in overall telescope weight and the need for less massive mounting capability.

Cool down also is reduced considerably due to the lowering of mass and, the large increase in surface area enabling much faster cool down times.

We also have the facilities to water jet cut glass, (and metal where needed) to non standard shapes.

All our elliptical secondary mirrors are initially cut to shape and size with water jet equipment to ensure regularity of shape and dimension.
