  1. Is Your Camera Fast Enough? 1/11/2011

    Infrared cameras fill the needs of specialized applications that cannot be fulfilled using standard visible cameras such as, night vision, thermography and non-destructive testing. By TELOPS

  2. Scientific CMOS (sCMOS) - Image Sensor Technology 6/18/2009
    sCMOS is a breakthrough technology developed by Andor Technology, Fairchild Imaging and PCO, and based on next-generation CMOS Image Sensor (CIS) design and fabrication techniques. sCMOS is poised for widespread recognition as a true scientific grade CIS, capable of out-performing most scientific imaging devices on the market today.

  3. Article: Measuring Lasers Used In Photovoltaic Solar Panel Manufacturing 5/25/2009
    Measuring the profile of a high power density beam with a small diameter can be tricky. Cameras are not very good at measuring beams with diameters of less than 50µm, and the attenuation required for the high power or energy densities can be substantial. The attenuation can also be a source of beam distortion, which adds great uncertainty to the data. By Photon Inc.

  5. Negative-Stiffness Vibration Isolation Gaining Popularity As The Need For Refined Imaging With Laser/Optical Systems Increases 4/23/2009
    Laser and optical systems, whether used in academic labs or industry, are very susceptible to vibrations from the environment and these instruments frequently need vibration isolation. When measuring a very few angstroms or nanometers of displacement an absolutely stable surface has to be maintained upon which to rest the instrument. Any vibration, coupled into the mechanical structure of the instrument, will cause vertical noise and fundamentally an inability to measure these kinds of high resolution features. By Jim McMahon
  6. White Paper: Properties & Reliability Of Improved Large Acceptance Optical Fibers 4/2/2009
    Laser based applications in micro-packaging, microelectronics, and optoelectronic manufacturing benefit from the use of optical fibers coupled to the laser sources. Both economical and technical benefits are possible. Efficient coupling is key to accepting laser beam energy into the fibers for many cases. In some cases the ability to spread the output may be the key factor. The availability of optical fibers having low optical losses and high numerical apertures provide the opportunity to use smaller dimensioned fibers while still maintaining highly efficient coupling.

  7. White Paper: Reliable Large Acceptance Optical Fibers For High Power Transmission 4/2/2009
    The UV and VIS spectral losses of high-OH Hard Plastic Clad Silica (HPCS) fiber were measured along with the NIR and VIS spectral losses of low-OH HPCS fiber with nominal core diameter for both types was 600 mm. High-OH fibers typically have >600 ppm of OH, while low-OH fibers typically have <2-4 ppm of OH. By CeramOptec Industries Inc.

  9. Choosing A Laser Beam Profiler 4/1/2009
    Laser beam profilers can be used with ultraviolet, visible, CW, high and low power, Infrared, and several other types of lasers in order to determine the laser beam’s spatial intensity profile. Because of the large array of laser types, there are several laser beam profilers available for measurement and beam diagnostics.
