First eight-meter Gemini mirror blank is fused

Corning Incorporated (Canton, NY) recently made the first of two mirror blanks for the Gemini Telescopes Project, which will use two 8-m mirrors in tandem. The 8.1-m-diameter mirror blank was made by fusing 55 hexagonal pieces of ultralow-expansion (ULE) glass in a 1700°C furnace.

A still from a video (link below) shows polymer microdisks being transferred to glass via laser catapulting. Laser catapulting can also be used to fabricate an array of microlenses directly on top of a photodetector array (inset), useful for directing more light onto the most sensitive parts of the detector.
