  1. Testing With Femtosecond Pulses
    3/19/2010
    Calmar’s femtosecond laser sources are passively mode-locked fiber lasers. Passive mode-locking makes these lasers easier to operate than actively mode-locked lasers, as no external RF clock signal is required, and little or no warm-up time is needed. Temperature control is also less of an issue with passive mode-locked lasers. By Calmar Laser, Inc.

    Image processing expert Vision Components introduces a multi-level approach which considerably facilitates programming for VC's intelligent cameras. All VC machine vision libraries have been revised to run on PCs. Customers can continue to program in C or C++, but can now also use the Microsoft development environment Visual Studio 2010.

  7. Better Nanoimages 'Spin' The Path To Improved Magnetic Memory
    3/16/2017

    In work that could help make possible a faster, longer-lasting and lower-energy method of data storage for consumers and businesses, researchers at the National Institute of Standards and Technology (NIST) and their colleagues have developed a technique for imaging and studying a promising class of magnetic devices with 10 times more detail than optical microscopes.

  8. What You Should Ask Before Investing In A Shortwave Infrared (SWIR) Lens
    1/30/2009
    The military and industrial communities are investigating shortwave infrared (SWIR) technology for new and improved imaging solutions for a variety of challenging applications. Indium gallium arsenide (InGaAs) is a material often used for SWIR imaging due to its high quantum efficiency and low dark current. This advanced InGaAs material makes these detectors the most sensitive imagers that operate in the shortwave IR wavelength range at any given temperature. By MARC HANSEN
