light scatteringparticle size measurementoptical particle counteraplanatic singlet lensWe have designed and constructed w white light optical snesor for optical particle counter (OPC). The optical system of the sensor is a right-angle scattering type optics. It consists of an illumination system and ...
Full size image This approach has several benefits. (1) Total-internal-reflection illumination enhances the illumination field strength at the interface and suppresses scattering from objects more than a few hundred nanometres from the interface, effectively reducing the sample-induced background. Crucial...
This novel experimental technique uses a super-continuum light source, an array of optical fibers, an imaging spectrometer and an EMCCD camera to simultaneously acquire wavelength and angle dependent particle light scattering data as a two-dimensional snapshot. Mueller matrix elements were initially ...
We present angle resolved photoemission spectra for Cu(100) and Cu(111) singly crystals in normal emission geometry, taken at tightly spaced intervals for photon energies between 8eV and 150eV. This systematic collection of spectra gives unprecedented insight into the influence of the final states ...
Full size image Calculation of the local strain tensor components To understand the possible origin of the studied SPEs, we analyze the local strain distribution in the nanoindent vicinity. In 2D crystals, the strain can be described by the in-plane tensor \(\hat{\epsilon }\)32: $${\epsil...
At least one commercial equipment, although rotating on a 360° angle, implements a mode of operation with fully offset detector, where thus every given point in the reconstructed volume is scanned for 180° half-rotation only but the diameter is two times larger than if the detector were ...

We demonstrate the use of a double-beam optical tweezers system to stabilize red blood cell (RBC) orientation in the optical tweezers during measurements of elastic light scattering from the trapped cells in an angle range of 5-30 degrees. Another laser (He-Ne) was used to illuminate the cel...
To confirm that XPA is a monomer at higher protein concentrations, we performed size exclusion chromatography coupled with multiangle light scattering (SEC-MALS). At 65 μM and 80 μM, purified XPA (His-flXPA-StrepII, 33.9 kDa) eluted in a single major peak, with a molecular ...
Note that the MIR illumination is set at the low-light level such that the average detected photon number per second is about one for each pixel. An stereo-structure overview is given in Supplementary Video 1 Full size image In the experiment, the 3D depth imaging is performed at different ...
