Irradiance

Materials Processing & Industrial Applications

Materials Processing & Industrial Applications

…Glass Engraving Coherent lasers are the ideal source for microstructuring inside glass. When marking and engraving glass, a high intensity laser irradiance enables a multi-photon process and non-linear absorption effects in transparent material such as flat panel display glass. The high peak power…

…into
a"box"profile which is based on two divergent aspheric cylinders that
purposely aberrates the beam to create a uniform far field irradiance
pattern. Intensity from the center of the Gaussian is redistributed to its
edges extremely efficiently. 1 or both axis can be shaped.…

…scattering is a valuable spectroscopic technique that can be applied to solid, liquid or gas samples. The Raman effect occurs when a sample is irradiated with UV, visible or IR light and a small fraction of the incident radiation is scattered and shifted at frequencies that correspond to vibrational…

ZeroClip Noise This option toggles the ZeroClip noise option on and off. When on,
any irradiance data with a negative value (after background subtraction) is set to zero (refer to Figure 3-12, above).

…a Fianium supercontinuum source has
allowed unprecedented characterization
of solar cells with its ability to generate a
dynamic irradiance spectrum, which can
mimic changes in time of day, time of year,
geographic location, and weather conditions, notes Taft (see Fig. 3).…

…membrane-embedded proteins. Opsins are switchable channels or pumps for specific
cations or anions whose on or off state is determined by irradiation with light of an appropriate wavelength. It has been known for decades that neurons transmit signals in the
form of an action potential or…

…setup
The experimental setup of VHIS is shown in Figure 6. The quantum dots sample was excited by a commercial UV
lamp with a peak irradiance output at 360nm. The fluorescent emission was collected by the 2:1 demagnification lens
pair whose function was to fit the whole sample into…
