Optical characteristics and compound technologies of multifunction protection goggles against laser radiation

To achieve effective protection against laser and microwave radiation,the compound technologies incorporating laser and microwave protection and laser warning were studied and this kind of multifunction protection goggles were designed. The key technologies include multifunction protection materials and compounded technology,sandwich type lenses compounded technology by means of heat press in vacuum,eye protection technology of resisting the splash induced by impact,adjustable protection eyeglasses technology between separated type and combined type.Multifunction protection performances of the developed protection goggles were tested.In addition,environment adaptability,laser biology effect and human-machine work efficiency were tested.The optical characteristics and compound technologies of multifunction integration protection goggles as well as relative techniques parameters were introduced.The experimental results show that ultraviolet transmittance of multifunction protection goggles is 0.0003～0.0005; relatively deviation of optical density of the goggles passing environment test and stored for 10 years is 0.0024～0.035; non-uniformity of optical density of the spectacles is 0.00059～0.0011;relatively deviation of optical density of the spectacles at laser incident angle of 0°～30° is 0.0061～0.012; relatively deviation of optical density of the spectacles at laser incident angle of 0°～30° is 0.0019～0.014 for laser exposure at different polarization directions; rabbit eyes wearing with the spectacles were not damaged at laser radiant exposure of(578.5～2405)mJ·cm-2.All performance indexes of this goggles accord with the demands of design and application.The multifunction protection goggles have good protective effect and can be used in the science research,teaching,manufacture,training and medical treatment.
