A large-aperture, piston-tip-tilt micromirror for optical phase array applications
2008 IEEE 21st International Conference on Micro Electro Mechanical Systems, 2008This paper reports the design, fabrication and characterization of a 4x4 micromirror array consisting of piston-tip-tilt electrothermal MEMS mirrors. Each mirror has an optical aperture size of 0.5x0.5 mm2. Both tip and tilt angles of over plusmn30deg are obtained at less than 5 Vdc, and the piston displacement reaches 215 mum at 4 Vdc. Two-dimensional

Optical free piston cell with constant diameter for use under high pressure
Review of Scientific Instruments, 1994An optical free piston cell (a modified le Noble and Schlott type optical cell) is described for use in spectrophotometric study under high pressure. The cell consists of a disk, a cylinder, and a free piston, which are made of quartz and are mounted within a stainless-steel holder. A small amount of sample solution (∼0.6 cm3), which only contacts with
