  • Teaching Analog New Tricks
    Many scanning, alignment and spectroscopy applications require optical power metrology coordinated with motion, with positioning precisions that often necessitate piezo-class motion devices. Unfortunately, traditional optical power meters show their "bench-top heritage" in their slow performance
  • How Does a Diopter Work?
    A diopter is a unit of measurement describing the optical power of a lens or curved mirror. When shopping for magnifiers, consider this: The diopter is equal to the reciprocal of the focal length measured in meters. For example a 5 diopter lens brings light rays to focus at 1/5 meter. Each diopter
  • 40Gb Ethernet QSFP+ Transceiver, Interoperable with 10GBASE-SR up to 100 m
    Avago Technologies is the fi rst fi ber optic module vendor to product release a fully compliant 40Gb Ethernet QSFP+. optical transceiver. Leveraging its history in delivering 850nm VCSEL based solutions, Avago QSFP+ modules deliver. excellent high speed optical / electrical performance coupled
  • The 5 Best Industry Applications For Linear And Rotary Solenoids
    solenoid is paired with optical shutters for medical device instrumentation or thermal and infrared camera systems, a rotary mechanism rotates the shutter each time the solenoid is energized with a pulse. The shutter remains latched until the opposite polarity pulse returns the shutter to starting
  • A Microfluidic System for Biological Particle Enrichment Using Contactless Dielectrophoresis
    of the buffer was. 130 mS/cm and was measured with a Mettler-Toledo SevenGo. pro conductivity meter (Mettler-Toledo, Inc., Columbus,. OH) to ensure that its conductivity was 130 ms/cm. These cells were observed to be spherical, with a diameter. of w13 mm when in suspension. Carboxylate-modified polystyrene
  • MSilica Nanoparticles Treated by Cold Atmospheric-Pressure Plasmas Improve the Dielectric Performance of Organic-Inorganic Nanocomposites
    . diameter beads that were carboxylate-modified polystyrene. microspheres (Invitrogen Molecular Probes, Eugene, OR,. USA) suspended in deionized water. The electrical conductivity. of the deionized water was determined using a MettlerToledo. SevenGo Pro conductivity meter (Mettler-Toledo,. Columbus, OH
