Hologram Method Boosts Additive Manufacturing
While traditional 3D printers work by depositing layers of material, tomographic volumetric additive manufacturing (TVAM) involves shining laser light at a rotating vial of resin until it hardens where accumulated energy exceeds a certain threshold. An advantage of TVAM is that it can produce objects in a matter of seconds, compared to approximately 10 minutes for layer-based 3D printing. But a disadvantage is that it is very inefficient, because only around 1% of the encoded light reaches the resin to produce the desired shape.

Photonics’ “Semiconductorization” Stands Out Among Trends at Photonics West 2025
It was surprising how far-removed Washington and political discussions appeared to be from this meeting of photonics experts from all around the world. Indeed, those who lost their travel grants on very short notice were missed (and colleagues who made it to San Francisco were alarmed). But even with the intense discussions on social media, politics ultimately became a secondary topic at Photonics West.

Simulating Nano-Optical Scattering Efficiently
Thu, Mar 13, 2025 2:00 PM - 3:00 PM EDT
The clever design of optical scattering characteristics in nanostructures has become a fundamental building block for breakthrough devices in high-speed telecommunication, biosensors, solar cells, AR/VR, and more. Accurately describing and predicting this behavior calls for full-wave simulations. Justus Bohn demonstrates how to easily set up a simulation model through an example that focuses on single-particle scattering. Furthermore, the discussion extends to typical nano-optical structures, such as diffraction gratings, metasurface deflectors, plasmonic structures, photonic crystals, distributed Bragg reflectors, and hyperbolic metamaterials. Presented by COMSOL.

Introduction to Imaging Radiometry and FLIR Research Studio
Thu, Mar 27, 2025 11:00 AM - 12:00 PM EDT
Discover the fascinating world of infrared imaging radiometry! Infrared imaging radiometry involves using an infrared camera to measure the infrared radiation emitted by objects in a scene. Each pixel in an image captured by a radiometrically calibrated camera provides quantitative data. These radiometric images are not just pictures; they are 2D grids of infrared radiation measurements from the scene, typically displayed as temperature per pixel in most commercial applications. During this webinar, Matthew Hasty will explore the fundamentals of infrared technology, how it works, and the various sensor technologies available. The presentation will also touch on radiometric calibration for temperature per pixel. Finally, Hasty will demonstrate how software, particularly FLIR Research Studio, can enhance efficiency and drive scientific discovery for global teams in innovative ways.
