Low-Cost, High Precision Technique Enables Thin Mirrors and Silicon Wafers
Researchers from MIT have developed a low-cost optical fabrication method that enables the production high-quality thin mirrors and silicon wafers. The method reshapes thin-plate materials in a way that eliminates distortion and enables researchers to bend surfaces more arbitrarily into the precise and complex shapes needed for high-level complex systems.

Combined Glass Fabrication Method Produces Complex Optics
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. École Polytechnique Fédérale de Lausanne researchers 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.

Team Looks to the LWIR to Fabricate Achromatic Metalens
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences demonstrated a broadband achromatic metalens with a numerical aperture of 0.32. The demonstration stemmed from a general method, proposed by the same team, to implement a broadband achromatic metalens in the LWIR band based on the combination of the dynamic and geometric phases.
