  • Flexible shield against laser radiation
    Patent number: 5219650
    Abstract: A thin flexible shield capable of preventing penetration by full powered medical laser beam is described. The shield is formed with a polymer matrix such as silicone rubber which is loaded with a substantial amount of particulate material. The material is selected to be non-toxic and non-burnable when exposed to a medical laser beam. The particle sizes are selected so as to enhance the ability of the shield to resist burn-through by a medical laser beam. Various materials and particle sizes are described with significant resistance to laser penetration encountered in structures that are as thin as about a millimeter with maximum power focused laser pulses.
