Lenses are crucial to light-enabled technologies. Conventional lenses have been perfected to achieve near-diffraction-limited resolution and minimal chromatic aberrations. However, such lenses are ...

Imaging and mapping of electric fields at radio frequencies currently requires structures about the same size as the wavelength of the RF fields to be mapped. New theoretical and experimental work ...

Widely tunable and high resolution mid-infrared radiation source operating in 3-5 µm region has been applied to numerous frontier applications, including remote sensing, molecular spectroscopy, and ...

US scientists have incorporated a nanowire laser into a prototype microscope that could enable biological samples to be imaged with sub-wavelength resolution. The prototype instrument, developed by ...

The Hamamatsu Picosecond fluorescence lifetime measurement system has been developed in response to the requirements of researchers studying such materials. The use of a "streak camera", an optical ...

Imaging and mapping of electric fields at radio frequencies (RF)* currently requires the use of metallic structures such as dipoles, probes and reference antennas. To make such measurements ...

Physicists in the US have built an acoustic lens from artificial “metamaterials” and used it to focus ultrasound waves to a tight spot. They say that modifying their apparatus could lead to very-high ...

Researcher Lillemeier wanted more detail on how the T-cell receptors are arranged in tissue and how that arrangement might change when the T cells are activated in living hosts. The team used a ...

Grenoble, FRANCE, May 12, 2016 - RESOLUTION Spectra Systems announces the worldwide release of LW-10: an innovative, very compact, high-resolution Laser Wavelength Meter for CW and pulsed lasers.

Newnan, GA. The new Yokogawa AQ6375B is an optical spectrum analyzer operating in the short-wavelength infrared region (SWIR), covering wavelengths from 1,200 to 2,400 nm. With a design based on the ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...
