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 ...

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 ...

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.

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

Spectral (or optical) resolution is one of the most essential characteristics of a spectrometer. A system’s spectral resolution determines the maximum number of spectral peaks that can be resolved by ...
