ITT







  Lightweighting of Mirrors

Waterjet glass cutting and low temperature fusion welding produce stable and distortion-free lightweight mirrors for spaceborne imaging systems. ITT has developed advanced techniques to fabricate mirrors with lightweight or honeycomb cores. These optic blanks weigh a fraction of a solid mirror blank, but achieve the stiffness and integrity required for critical applications. Our state-of-the-art techniques have produced mirror blanks with an arial density of 9 kg/m2.
