A manufacturing technique for creating microstructures by integrating two types of glass with different physical properties could provide a path to complex infrared (IR) optics to be used in spectroscopy, imaging, sensing, and other applications. Researchers at École Polytechnique Fédérale de Lausanne (EPFL) developed the technique. It can be used with a variety of glass types to create almost any 3D shape with features measuring 1 μm or less. The researchers created microscale, freeform, 3D chalcogenide microstructures embedded in a fused silica matrix....Read full articleRelated content from Photonics MediaARTICLESAI to Automate Laser Material DepositionIndustrial organizations in Germany and Canada are collaborating to provide automated control of laser material deposition (LMD) and other additive processes using artificial intelligence (AI).

Each approach exhibits advantages and disadvantages, depending on the type of light detector and acquisition method employed.The term fluorescence is often applied as a synonym for photoluminescence, although luminescence actually covers fluorescence and phosphorescence. Both of these terms describe the process of...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot.
