A honeycomb mirror is a large mirror usually used as the primary mirror in astronomical reflecting telescopes whose face is supported by a ribbed structure that resembles a honeycomb. [2] The design provides sufficient rigidity for ultra-high-precision optics while reducing the weight of the mirror. The reduced weight, in turn, allows smaller ...

The Keck II Telescope showing the segmented primary mirror made of Zerodur. The main applications for Zerodur include telescope optics in astronomy [2] and space applications, [3] lithography machines for microchips and displays, [4] and inertial measurements systems for navigation.
Images from telescopes with segmented mirrors also exhibit diffraction spikes due to diffraction from the mirrors' edges. As before, two spikes are perpendicular to each edge orientation, resulting in six spikes (plus two fainter ones due to the spider supporting the secondary mirror) in photographs taken by the James Webb Space Telescope .
