𝗦𝗽𝗮𝘁𝗶𝗮𝗹 𝗙𝗶𝗹𝘁𝗲𝗿𝗶𝗻𝗴 𝗶𝗻 𝗢𝗽𝘁𝗶𝗰𝗮𝗹 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗳𝗼𝗿 𝗛𝗶𝗴𝗵-𝗤𝘂𝗮𝗹𝗶𝘁𝘆 𝗟𝗮𝘀𝗲𝗿 𝗕𝗲𝗮𝗺𝘀 Spatial filtering is a crucial technique in optics for refining laser beams, enhancing their quality, and minimizing aberrations and unwanted diffraction effects. By employing a combination of lenses and apertures, spatial filtering selectively removes unwanted components such as noise, diffraction patterns, and spatial irregularities from the laser beam. This process ensures a more uniform intensity distribution, reduces divergence, and enhances coherence, leading to improved beam quality. Spatial filtering is indispensable in various applications including #laser machining, #holography, #microscopy, and #telecommunication, where precise control over beam characteristics is essential for optimal performance and accuracy. #VirtualLabFusion 's unique simulation techniques enable users to model filtering in detail, thereby allowing them to assess the impact on the performance and characteristics of the optical system.

Soft/hard differentiation of surface features at the nanoscale! I've been working on #biomaterials surfaces recently with the #afm and got nice information from phase imaging. One of the unique features of AFM is that it can give you nano-mechanical information about a surface, the easiest being the phase image. You get an immediate idea of what's on your surface and it's particularly useful for co-polymers of different stiffness. https://lnkd.in/ei8erwjq

New Nano-CT SkyScan 2214 successfully put into operation As part of the DELFIN joint project, we have acquired a new type of X-ray microscope (“nano-CT”) to examine the electrode structure of a modern lithium solid-state battery using 3D imaging. The SkyScan 2214 CMOS from Bruker offers true spatial resolution down to the submicrometer range of 0.5 µm. What's special about it: The device's precise phase contrast imaging significantly improves the contrast in multiphase microstructures. This makes the SkyScan 2214 ideal for the microscopic analysis of electrode structures in lithium solid-state batteries. #Bruker #BrukerAXS #MicroCT #NanoCT https://lnkd.in/ek4DFk_r

Say goodbye to bulky laser safety gear! Our new research paves the way for self-activating optical limiters. #Innovation #MetaOptics #TMOS ABSTRACT: Protection of human eyes or sensitive detectors from high-intensity laser radiation is an important challenge in modern light technologies. Metasurfaces have proved to be valuable tools for such light control, but the actual possibility of merging multiple materials in the nanofabrication process hinders their application. Here we propose and numerically investigate the opto-thermal properties of plane multilayered structures with phase-change materials for optical limiters. Our structure relies on thin-film VO2 phase change material on top of a gold film and a sapphire substrate. We show how such a multi-layer structure can act as a self-activating device that exploits light-to-heat conversion to induce a phase change in the VO2 layer. We implement a numerical model to describe the temporal evolution of the temperature and transmittivity across the device under both a continuous wave and pulsed illumination. Our results open new opportunities for multi-layer self-activating optical limiters and may be extended to devices based on other phase change materials or different spectral regions..

Twyman-Green Interferometers are interferometers used to test optical components. It was invented by Frank Twyman and Arthur Green in 1916. It is used to measure the surface shape and transmitted wavefront quality of optical components, assemblies, systems, and optical-grade mechanical surfaces. A point-like light source such as lasers or LEDs is used in the Twyman-green interferometer.
