Measuring Optics with Spectrally Controlled Interferometry
Measuring flat and prismatic optics with a traditional laser interferometer is difficult to impossible. Optical engineers, scientists, and technicians struggle to obtain accurate measurements on optics with two or more flat and parallel optical surfaces because of mutually interfering back reflections. This mutual interference can degrade or hinder measurement, making it difficult to tell whether a part meets specification.

Li-Fi Adds Data to Light the Way
Light fidelity, or Li-Fi, is a visible light communication (VLC) system first introduced in 2011 by Harald Haas, a researcher from the University of Edinburgh. The system utilizes LEDs, which emit visible spectrum light with brightness that can be precisely controlled and modulated at very high speeds — so quickly that the light pulses go undetected by the human eye. Thus, users benefit from the seemingly unflickering illumination of Li-Fi-enabled LED light bulbs, while data is simultaneously transmitted at speeds potentially faster than Wi-Fi.

Data Needs Drive Underwater Fiber Developments
Data traffic will nearly double in the next three years, according to analysts. Many bits will travel between data centers over land, and many will make the long journey across the ocean, moving through fiber optic cables that sit on the seafloor. An estimated 1.2 million km of submarine fiber is in use today. Government statistics indicate that nearly all international data traffic, perhaps as much as 99 percent, travels via submarine cable, with satellite transmissions making up the rest. Submarine fiber cables are more economical for moving data than satellites.

A Bird’s-Eye View of AR Coatings, from Concept Through Production
Tue, Mar 12, 2019 1:00 PM - 2:00 PM EDT
This webinar will present the concepts and design principles of antireflection (AR) coatings, the most common optical thin-film coating produced today and for more than 80 years. It will discuss the equipment used in AR coating production and the process aspects of AR coatings. Many other types of coatings have evolved from these same principles, equipment, and processes, and these will be touched on briefly, but the focus of the webinar will be on AR coatings. The webinar is sponsored by North American Coating Laboratories and Satisloh GmbH.
