Multifunction protection goggles against laser radiation

In order to reduce and avoid damage form laser and microwave, multifunction protection goggles, incorporating protective systems against laser and microwave and an integrated warning system was developed. The goggles consist of some optical parts and photoelectron modules that perform a specific function, which include multifunction protective lenses, frames and laser detection-alarm systems. The key compounded technologies of multifunction protection were studied and protective performance of the spectacles was tested. The result shows that the optical density of this goggles is from 4.0 to 7.28 at the laser wavelength of 532nm, 1064nm，790nm and 840nm; integral transmittance of visible light is 18.7%; attenuation value of microwave radiation is more than 20dB; the warning system can provides an automatic detecting and sound-light warning at the laser wavelength of 532nm, 1064nm and 840nm; detecting sensitivity of alarm is 10-7J/cm2; this goggles can resist impact against steel-ball splinter whose mass is 1g, speed between 300m/s and 400m/s; gross weight of the goggles is less than 200g. In addition, the spectacles have characteristics of wide range of protection wavelength, higher attenuation rate for laser and microwave, bigger protection angle, higher transmittance for visible light, usage of separated type and combined type, smaller size, light-weight and convenience to wear. They not only can protect an individual operator against laser and microwave radiation, but also can protect photo-electric sensors. They are also necessary protection equipment in modern optical experiment as well as terrorism opposition and public safety.
