20130029098 | OPTICAL INTERFACE FOR REDUCED LOSS IN SPINEL WINDOWS - A method for reducing transmission losses in a spinel-based optical element by building a structure on the surface of the optical element without the use of a previously prepared master. The structure can be built through reactive ion etching (RIE) of a pattern obtained through photolithography and liftoff, through RIE of a pattern through e-beam writing and liftoff, through RIE of a pattern using a self organized metal mask, or by direct hot-pressing the structure during fabrication of the optical element. Also disclosed is the related spinel-based optical element made by this method. | 01-31-2013 |
20130160492 | POLISHED, HOT PRESSED, NET SHAPE CERAMICS - A method for making a smooth ceramic including loading ceramic powder to be densified into a hot press die, placing one or more spacers with a polished surface between a hot press punch and the ceramic powder, placing the die and punch into a hot press and hot pressing the ceramic powder, and removing a smooth ceramic shape that requires no subsequent polishing or processing and has a surface roughness of 5 nm RMS or better. The smooth ceramic shape may be transparent, and it may be spinel, magnesia, yttria, lutetia, scandia, YAG, any composites thereof, or any of their rare earth doped compounds. Also disclosed is the related smooth ceramic made by this process. | 06-27-2013 |
