Israel: Advanced anti-laser filter announced
08 May 2012 -- Categories: Anti-laser protection | SLA news
A newly developed anti-laser filter works by blocking laser light based not just on the wavelength (color) as with traditional filters, but based also on the light level (irradiance). KiloLambda Technologies of Tel Aviv says their filter “is clear at all wavelengths until it is hit by an incoming power above a certain level. Below the threshold, the filter has high transmission over the whole spectral band, but when the input power exceeds the threshold, transmission is either limited to a certain value or blocked completely."
It is not clear whether the filter is available at this time (May 2012). The company intends to incorporate it into glasses and night-vision goggles worn by pilots, to protect against flash blindness, meaning power densities from 100 µW/cm² up to 1000 µW/cm².
