Abstract
A light transmission apparatus in which light from a laser may be transmitted through an optical conducter. Dry air may also be pumped through the optic conducter to remove matter from the vicinity of the light emitting end. A cover which is formed of a shape memory alloy is provided at the light emitting end of the conductor to open at a high temperature in response to incident light and close at a low temperature when the light stops.
