SAMPLE MONITORING

Dual-comb photothermal spectroscopy (DC-PTS), demonstrated for the first time by a joint team from the Chinese University of Hong Kong and the Changchun Institute of Optics, Fine Mechanics and...

Far above an oil pipeline, a drone bobs and weaves. The drone, dispatched by Denver, Colorado-based Project Canary, is collecting high-resolution imaging data of the site, while also scanning for any...

Researchers at the Korea Research Institute of Chemical Technology (KRICT) developed a transparent protective coating material that can self-heal in 30 minutes when exposed to sunlight. ...

To achieve performance gains in microelectronics, semiconductor size continues to shrink, with feature sizes now in the sub-10-nm range. The challenges associated with the extreme downscaling of...

The optical materials selected for an optical system depend upon the application, the required system performance and the environment in which the system is to perform; thus the materials’...

What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...

Single-crystal sapphire has been the material of choice for defense and other applications that require extremely durable optics, but aluminum oxynitride (ALON) and magnesium aluminate (spinel) have...

Free Webinar presented by Photonics Media & OSA Additional Questions and Answers from the Webinar below: Wayne Lem Market Manager Trojan Technologies From the water we drink to...

The analysis and characterization of important objects can be challenging due to their location and accessibility. The noninvasive and nondestructive analysis of such objects is critical for...

The optical performance of optical coatings is only half of the picture. A coating that is perfectly manufactured to meet its optical specifications is useless unless it also meets the application's...

Non-destructive, portable, and extremely discriminating in its analysis -- Raman spectroscopy has established itself as a powerful tool in the identification and quantification of chemicals in...

Flow chemistry, also known as continuous-flow chemistry, is a chemical manufacturing process where reactions take place in a continuous stream of fluids (liquids or gases) rather than in batch...

The process, used with a positive photoresist, in which the photoresist is immersed in developing chemicals while being exposed to the optical pattern. The newly exposed surface is continuously...

The use of chemicals or radiation to induce a desired change in a substance; e.g., some optical adhesives are set by exposure to ultraviolet light and are said to be UV-curing.

Silicon carbide (SiC) light-emitting diodes (LEDs) are semiconductor devices that emit light when an electric current is applied to them. These LEDs are made using silicon carbide as the...

Video definition of dispersion presented by Dr. Gerard Wysocki, Princeton University.

A laser dye is a class of organic dyes that emit coherent radiation over a wide spectral range.

“Name the application, we have solutions,” is more than a slogan. It’s what keeps Universal Photonics a world-leader in critical surface preparation material, processing machinery...
