Cameras, eyes, telescopes, binoculars and night vision goggles can all be dazzled and damaged by high energy light pulses, but a new liquid crystal filter could block that while still providing enough light for good picture quality.
‘Class 3B and Class 4 lasers represent a serious hazard to the eyes and skin. Additionally, Class 4 lasers have the potential to damage surrounding infrastructure,’ says Paul Tozer, managing director of laser safety solutions company Lasermet. Rising to the challenge of these increasingly powerful lasers with more comprehensive protection for users and their facilities is driving advances in the safety market.
Modern microscopes are highly advanced pieces of equipment allowing scientists to probe deeper into tissue and resolve ever finer structures. Super resolution microscopy techniques, such as photoactivated localisation microscopy (PALM) or stimulated emission depletion microscopy (STED), are the current state-of-the-art, providing higher resolution than standard confocal microscopes. Confocal microscopes are typically diffraction limited to around half the wavelength of the illumination source.
Lasers have been used for aesthetic treatments in the clinical environment for many years for procedures such as hair removal, skin rejuvenation and even liposuction. Now, with advances in miniaturisation, aesthetic laser treatments are finding their way into the home. The first application to make the leap from clinic to consumer was hair removal – light-based home-use devices for hair removal can now be found on store shelves next to the hair straighteners, electric toothbrushes and epilators.
Lasermet is celebrating 25 years in the laser industry, and has earned a reputation as one of the leading names in laser safety in the UK and beyond.
Back in 1987, Professor Bryan Tozer had taken early retirement from a career at the Central Electricity Generating Board (CEGB), where he had spent 17 years as the organisation’s laser safety officer.
His involvement and experience in laser safety led him to become chairman of the BSI Laser Safety Committee (a post he held until 2008). He later also be became chair of the European Laser Safety Committee for 16 years.
