OMC Announces New Ultra-High-Efficiency IR SMA Fibre-Optic Transmitter LED - FDE870HE
OMC, the pioneer in optoelectronics design & manufacture, announces its new FDE870HE industrial fibre optic transmitter LED that can deliver up to four times more launch power into multimode fibre for the same current versus existing transmitter devices. This ultra-efficient transmitter contains a high-performance 870 nm chip and features an array of micro-optic elements that gather and focus the emitted photons, coupling considerably more light into multimode optical fibres and enabling data to be transmitted reliably over greater distances, or for the system to use less power to achieve the same result. Greater long-term reliability of the system is a further benefit due to the vastly enhanced day-1 launch power and much lower drive current requirements.

Precise Measurement of UV Light Sources for Disinfection
UV radiation encompasses a very wide wavelength spectrum between 10 and 400 nm and is subdivided in ISO Standard 21348 into three ranges. The UVC range between 100 and 280nm is currently extremely relevant for air and water disinfection for combating COVID-19. Since the outbreak of the pandemic this has been manifested, among other things, in a sharp increase in the demand for UVC light sources.

CIE Position Statement on the Use of UV Radiation to Manage the Risk of COVID-19 Transmission
The coronavirus disease (COVID-19) pandemic has accelerated the search for environmental controls to contain or mitigate the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the disease. SARS-CoV-2 is usually transmitted from person to person by contact with large respiratory droplets, either directly or by touching virus-contaminated surfaces (also denoted as fomites) and subsequently touching the eyes, nose or mouth. Importantly, there is growing evidence of virus transmission via the airborne route as the large respiratory droplets dry out and form droplet nuclei which can remain airborne for several hours. Depending on the nature of the surface and environmental factors, fomites can remain infectious for several days (van Doremalen, 2020).
The use of germicidal UV radiation (GUV) is an important environmental intervention which can reduce both contact spread and airborne transmission of infectious agents (like bacteria and viruses). GUV within the UV-C range (200 nm–280 nm), primarily 254 nm, has been used successfully and safely for over 70 years. However, GUV must be knowledgably applied with appropriate attention to dose and safety. Inappropriate GUV application can present human health and safety issues and produce insufficient deactivation of infectious agents. Application in the home is not advisable and GUV should never be used to disinfect the skin, except when clinically justified.
