Abstract
Abstract A protective glove is formed of composite material for close fitting over the fingers and the back and palm of the hand. The composite material includes a layer of flexible elastic material for tactile sensitivity through the layer. Optically reflective and dispersive particles are distributed and embedded within the layer for dispersing incident laser light thereby preventing laser burn injuries to the hand of a wearer.

Claim 11
Dependent Claim
57 words
The protective glove of claim 1 wherein the dispersive particles are distributed and embedded in the layer of flexible elastic material with a relatively higher density distribution in the area of the back and palm of the hand of the glove and with a relatively lower density distribution in the area of the fingers of the glove.
Claim 12
Dependent Claim
54 words
