  • LaCie releases 20TB Thunderbolt RAID array-Singapore Optics Shop-http://www.optics.sg
    together Thunderbolt announced by Intel last year offers twice the performance of the latest SuperSpeed USB 3 0 interconnect So there is reason to believe it could someday overtake USB the most ubiquitous external I O technology ever created LaCie which was acquired by Seagate earlier this year said the new RAID array features speeds of up to 785MB sec through the use of five 7200rpm hard disks that have 64MB of cache each Three of the 5big Thunderbolt s drives are configured in RAID 0 which writes data to two or more disks in order to increase performance and not resiliency The remaining two drives are configured in RAID 1 or single redundancy for data resilience The array can also be set up as JBOD Disk drives are also hot swappable so the user can simply slide a new disk into the safe volume without switching off the device The array comes with dual cooling fans The box which comes preconfigured in RAID 0 is being aimed at small businesses and video professionals working in need post production settings because the array offers them the ability to edit multiple 2K uncompressed 10 bit streams LaCie said its 5big array allows video professionals to move from a heavy desktop workstation to more mobile and versatile laptop setup with faster and higher capacity storage Their desktop setup stays in the office while the laptop goes on business trips LaCie stated Configured as JBOD LaCie s 5big can also be used for daily backup which one disk assigned for each day of the week the company said It is an ideal backup companion to a Mac Mini Server for businesses that need a professional IT setup LaCie stated in a news release LaCie s 5big Pricing for the LaCie 5big which comes

  • Principle of Waveplate -Singapore Optics Shop-http://www.optics.sg
    in velocities gives rise to a phase difference when the two beams recombine In the case of an incident linearly polarized beam this is given by a 2pi d ne no l a phase difference d thickness of waveplate ne no refractive indices of extraordinary and ordinary rays respectively l wavelength At any specific wavelength the phase difference is governed by the thickness of the retarder Transmission range 330nm 2100nm Thermal Expansion Coefficient 7 5x10 6 K Density 2 51g cm3 Half Waveplate The thickness of a half waveplate is such that the phase difference is l 2 wavelength true zero order or some multiple of l 2 wavelength multiple order A linearly polarized beam incident on a half waveplate emerges as a linearly polarized beam but rotates such that its angle to the optical axis is twice that of the incident beam Therefore half waveplates can be used as continuously adjustable polarization rotators Half waveplates are used in rotating the plane of polarization electro optic modulation and as a variable ratio beamsplitter when used in conjunction with a polarization cube Quarter Waveplate The thickness of the quarter waveplate is such that the phase difference is l 4 wavelength true

  • “Cakes” of Carbon Nanotubes Could Measure Terahert-Singapore Optics Shop-http://www.optics.sg
    NIST Boulder Colo U S A created arrays of extra long carbon nanotubes that absorb virtually all radiation at these wavelengths an important step in designing appropriate radiometric detectors Appl Opt 50 4099 John H Lehman and his colleagues grew three different lengths of multi walled carbon nanotubes all aligned perpendicular to their silicon substrates These tiny tubes were 40 m 150 m and 1 5 mm 1 500 m tall Multi walled tubes have more uniform radiance properties than the single walled nanotubes do Next the NIST scientists measured how much light these arrays reflected from a 394 m gas laser beam close to the middle of the terahertz part of the spectrum As they expected the longer the nanotubes the less radiation they reflected about 0 01 percent for the 1 5 mm tall array with much higher absorption in the far infrared than comparable proprietary coatings According to the NIST group the thermal decay time of the nanotube arrays is also relatively low compared to these black coatings On a practical level the height of the 1 5 mm nanotube forest made it easy for humans to see the arrays without a microscope and to move them
