The might of metasurfaces

Harvard researchers have developed a metasurface that can effectively tune the properties of laser light without the need of additional optical components

LASER GAS LEAK DETECTION WITH INFRARED

This article is brought to you by: 

High progress in optoelectronics technology, especially designed for infrared wavelength region (IR), is observed. The use of various spectroscopic methods allows to obtain detailed information on the chemical analysis of the leaking gas. Each of the spectroscopy methods is dedicated to different types of concentration measurements. We encourage you to read the article that explains and presents laser gas leak detection with infrared.
