Researchers in Germany have developed an optical coating system that combines antifogging and antireflective properties. The new technology could help boost the performance of lidar systems and ...

Anti-Reflection (AR) coatings represent a key innovation in optics. AR coatings are central to the proper manipulation of light, mitigating Fresnel reflection, enhancing system throughput and ...

A project at NIST has developed a new way to monitor and assess 3D printing of metals. Finding and correcting defects inadvertently created inside a 3D printed part is one of the biggest challenges ...

Geometric optics explains how light behaves when it reflects, refracts, and forms images through lenses and mirrors. From total internal reflection in fiber optics to the sparkle of rainbows, these ...

Refractive index measurement is at the heart of optical science, influencing everything from lens design to material characterization. Modern techniques span from classical prism-based methods to ...

Researchers combine a polymer coating with silicon dioxide nanostructures to create a coating to prevent fogging and unwanted reflections. The technique solves a common problem for sensors such as ...
