UV Light In Forensics
Forensic investigators and researchers utilize a variety of light sources to examine the evidence found at a crime scene. Among a plethora of light sources, Ultraviolet (UV) light, in particular, has gained a positive reputation for efficient and effective examination of biologically contaminated evidence. As [...]
Tracking Counterfeit Currency With The Help Of Bill Counters
It is not every day that businesses deal with the problem of receiving counterfeit currency. Be that as it may, this act of forgery — despite its infrequency — cannot be overlooked. It goes without saying that this deliberate attempt to defraud the receiver is fraudulent, and that makes it [...]
Ultraviolet Irradiation
Recent studies have shown that a wide variety of such contaminants exist at trace concentrations in all water supplies and in the air. Ultraviolet germicidal irradiation (UVGI) is a method of disinfection that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their [...]
Choosing Ultraviolet Energy For Wastewater Disinfection
Ultraviolet or UV energy is found in the electromagnetic spectrum between visible light and x-rays and can best be described as invisible radiation. In order to kill microorganisms, the UV rays must actually strike the cell. UV, or ultraviolet light, disinfects waste water by damaging the DNA and RNA of [...]
Spectroscopy Explained
The study of the interaction between matter and electromagnetic radiation is known as spectroscopy. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. Spectroscopic data is often represented by an emission spectrum, a plot of the response of interest as a function of wavelength or frequency. [...]
Li-Fi Technology
Li-Fi is a technology for wireless communication between devices using light to transmit data and position. In technical terms, Li-Fi technology – visible light communication system – is capable of transmitting data at high speeds over the visible light spectrum, ultraviolet and infrared radiation. The term Li-Fi was coined by University of Edinburgh Professor Harald Haas during a TED Talk in 2011. [...]
Spectrally Controlled Interferometry
A recent advancement in the technology of the traditional interferometer, spectrally controlled interferometry (SCI), improves the manufacturing of optics that has multiple flat surfaces. […]
Hydro-Optic Disinfection (HOD) UV Technology
In 2014 facing ongoing water contamination issues, Plant Bowen Water Research Center, opted for a full-scale trial of Hydro-Optic Disinfection (HOD) UV technology to help find a viable solution. […]
Treat Water With UV Rays
Swimming pool service professionals have long known that the water in a pool can be treated by utilizing ultraviolet (UV) rays instead of, or in addition to, pool chemicals such as chlorine. A new process has been adapted that can quickly break down pollutants in wastewater, swimming pool or drinking [...]
Purify Water With UV Rays
One of the most effective means of purifying water is through the use of ultraviolet (UV) rays. UV rays can disinfect water and kill bacteria, it can also penetrate any harmful pathogens in drinking water and destroy the microorganisms that can cause illness. The way UV rays work is by [...]
