A catadioptric telescope is an optical system that is optimized for producing images of objects at an infinite distance, and which incorporates both refractive type optics(lenses) and reflective optics(mirrors). The use of both mirror and lens optics produces certain advantages in performance as well as in the manufacturing process.  3, record 1, English, - catadioptric%20telescope

We report on the casting of the first 8. 4 meter diameter borosilicate honeycomb mirror at the Steward Observatory Mirror Laboratory. This blank will become the world's largest monolithic glass telescope mirror, and is the first of two mirrors for the Large Binocular Telescope Project. The honeycomb 8. 4 meter mirror was cast from 21 tons of E6 borosilicate glass manufactured by Ohara. This glass is melted into a mold constructed of aluminosilicate fiber to produce a honeycomb structure with roughly 20% of solid density. The 1662 hexagonal voids that form the honeycomb structure are produced by ceramic fiber boxes bolted to the bottom of the mold with SiC bolts. The furnace rotates at 6. 8 rpm during the casting process to produce the F/1. 14 paraboloid on the front surface. This shaping minimizes the amount of glass which must be removed during the grinding process. The front faceplate of the mirror will be 28 mm thick after generating and the back faceplate will be 25 mm. The overall thickness of the finished honeycomb blank is 89 cm at the outer edge and 44 cm at the central hole.  3, record 4, English, - honeycomb%20mirror

Les premiers «grands» miroirs ont été coulés pour le MMT (ex Multi Mirror Telescope), puis pour les deux télescopes Magellan de 6.50m, et en ce moment, pour le premier des deux miroirs de 8,4m du LBT (Large Binocular Telescope).  2, record 4, French, - miroir%20alv%C3%A9ol%C3%A9

Mirror site : because the Internet population has exploded in recent years, a lot of archive servers can’t cope with the load. One solution is to create an exact copy of a server--a process called mirroring. Mirror sites divert some of the traffic from the original site. It's not unusual to find a dozen or more mirrors of busy ftp sites.  2, record 5, English, - mirror

Ring laser gyro... The mechanical structure integrity of the gyro is based on a 1. 2 X1. 2 meter block of zerodur. The zerodur is a glass ceramic material with a thickness of 180 mm weighing approximately 600 kg. The block has four 1-meter longitudinal bores provided for the laser beam paths. Folding mirrors are mounted at each of the four corners of the block. This forms a closed square resonator in which the laser beams can travel in both directions. The block was produced by Zeiss Glaswerke of Mainz, Germany. At Zeiss the machining process included cutting the gyro body edges in preparation for the mounting of the folding mirrors. The surfaces for the mirror mounting are optically polished allowing the folding mirrors to be attached directly to the zerodur by optical contact rather than by bonding.  3, record 7, English, - gyro%20body
