ASTRONOMY: Aitious mid-IR telescope makes short …

Webb uses beryllium in its deployable mirror, and Herschel’s mirror is asseled from 12 segments of sintered silicon carbide. The surface tolerance for SPICA’s mirror is an order of magnitude tighter than for the longer-wavelength Herschel, so developers are evaluating performance of carbon-fiber-reinforced silicon carbide as well as sintered silicon carbide.

2. Optical Fabriion of Silicon Carbide However, RB-SiC is typically a difficult material to machine. SiC is harder than most other materials except diamond, cubic boron nitride (cBN), and boron carbide (B 4 C), and hence available cutting tool materials for machining RB-SiC are very limited.

Long Range Reconnaissance Imager - Wikipedia

Long Range Reconnaissance Imager (LORRI) is a telescope aboard the New Horizons spacecraft for imaging. LORRI has been used to image Jupiter and its moons and especially Pluto and its system of moons since its launched in 2006. LORRI is a reflecting telescope of Ritchey-Chrétien design, and it has a main mirror diameter of 20.8 cm (8.2 inches) across.
