Scientists in China developed a method for preparing porous SiO2 materials by combining electron beam co-evaporation with selective chemical etching. Based on this method, all-silica ultraviolet laser ...

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 ...

The basics of fiber optic cables and bundles and how they can be used to collect and direct light are discussed in ‘An Introduction to a Spectrometer: Fiber Optic Bundles’. This article will discuss ...

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 ...

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 ...
