摘要

An optical fuse contains a thin metal film that reflects ordinary light, but is damaged when the light intensity becomes too high, so that the light no longer reflects. Optical fuses can be used to protect eyes or sensors against dangerous laser radiation. In order to be suitable for use in an optical fuse, a metal film should have high reflectance when exposed to ordinary light intensities, but very quickly get damaged, so that the reflectance becomes low when exposed to dangerous light levels. In this diploma work, different metals and film thicknesses have been investigated, to find suitable films for this purpose.
