A look at UV sterilisation and how advances in optical filters for illumination have opened up new applications by alleviating safety concerns
This white paper offers an in-depth look at UV sterilization, including how the latest developments in filter technology have improved the safety of sterilization devices, and presents a number of use cases.
Laser Components is expanding its portfolio of UV LEDs with products from the South Korean manufacturer Photon Wave
Current worldwide conditions have brought a renewed focus on ultraviolet or UV based sterilization systems. UV light has been shown to kill many types of pathogens. A key metric is the dose, or amount of UV light on a surface, as a minimum dosage level is required for effective sterilization. Using optical analysis software as part of the design process ensures that these minimum dosage levels are obtained.
The UK's largest airport will use UV robots at night to kill viruses and bacteria
The authors suggest that placing UVC light sources at ventilation systems and rooms not in use, without direct optical paths to humans, helps reduce virus propagation. Credit: Nacho Gaubert
A study involved experts in the fields of virology, immunology, aerosols, architecture, and physics, analyse possible methods to prevent Sars-Cov-2 propagation indoors

An LED irradiation system has been developed at the Ferdinand-Braun-Institut in Berlin that aims to kill microorganisms with ultra-short wave UV light. The researchers anticipate that the UV light emitted from their device will not be harmful to human skin
With increased interest in using UV light to deactivate viruses, Robert Yeo, director at Pro-lite Technology, discusses the safety and effectiveness of UVC devices
The robots guide themselves around hospital rooms irradiating surfaces with UV light, which disinfects and kills viruses and bacteria.

As microscopes become ever more powerful, a growing band of businesses are racing to make the latest technologies more accessible and more affordable, reports Rebecca Pool
Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
