2. Phased-array optics - Wikipedia

   en.wikipedia.org/wiki/Phased-array_optics

   An optical phased-array transmitter includes a light source (laser), power splitters, phase shifters, and an array of radiating elements. [4] [5] [6] The output light of the laser source is split into several branches using a power splitter tree. Each branch is then fed to a tunable phase shifter.

3. Hollow-cathode lamp - Wikipedia

   en.wikipedia.org/wiki/Hollow-cathode_lamp

   Basic diagram of a hollow-cathode lamp Hollow-cathode lamps from an atomic absorption spectrometer. A hollow-cathode lamp (HCL) is type of cold cathode lamp used in physics and chemistry as a spectral line source (e.g. for atomic absorption spectrometers) and as a frequency tuner for light sources such as lasers.

4. Laser trimming - Wikipedia

   en.wikipedia.org/wiki/Laser_trimming

   Laser trimming is the manufacturing process of using a laser to adjust the operating parameters of an electronic circuit. Laser-trimmed precision thin-film resistor network from Fluke, used in the Keithley DMM7510 multimeter. Ceramic backed with glass hermetic seal cover. Laser trim marks are visible in the grey resistive material.

5. Spectralon - Wikipedia

   en.wikipedia.org/wiki/Spectralon

   A Spectralon panel. Spectralon is a fluoropolymer that has the highest diffuse reflectance of any known material or coating over the ultraviolet, visible, and near-infrared regions of the spectrum. [1] It is the whitest substance available and reflects 99% of the light.

6. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).

7. Photonics Spectra - Wikipedia

   In 1967, in response to industry demands, she founded and launched Optical Spectra. In 1982 the magazine's name was changed to Photonics Spectra to reflect the growing influence of these new light-based technologies. [1] Today, the worldwide distribution of Photonics Spectra is over 100,000 copies. [2]

8. Spectrum Brands - Wikipedia

   en.wikipedia.org/wiki/Spectrum_Brands

   On January 16, 2018, the Rayovac division was bought by Energizer for $2 billion. [6] On February 26, 2018, Spectrum Brands announced it was merging with controlling shareholder HRG Group, Inc. The move would not affect the pending sale of its battery division to Energizer. Spectrum management was expected to run the merged entity. [4]

9. Resonance-enhanced multiphoton ionization - Wikipedia

   en.wikipedia.org/wiki/Resonance-enhanced_multi...

   In contrast to optical heterodyne techniques, no alignment or mode matching of the reference is necessary. The long wavelength of the microwaves leads to effective point coherent scattering from the plasma in the laser focal volume, so phase matching is unimportant and scattering in the backward direction is strong.
