Abstract
A laser-light shield including a metallic substrate having uneven surface and a flame-sprayed film formed on the uneven surface and essentially consisting of metal oxide. The shield is useful for shielding a human body from laser light.
Claims22
A laser-light shield having a flame-sprayed metal-oxide ceramic film on a metallic substrate, wherein a surface of the metallic substrate, on which the flame-sprayed metal-oxide ceramic film is applied, has an unevenness having a height greater than the thickness of the flame-sprayed metal-oxide ceramic film, and, said flame-sprayed metal-oxide ceramic film has a top surface shape which essentially reproduces said unevenness.
A method for shielding a human body from laser light, comprising the steps of:
- preparing a laser-light shield comprising a metal plate having an unevenness on a surface thereof and a flame-sprayed film of a metal oxide applied on said surface of the metal body, said unevenness having a height greater than the thickness of the flame-sprayed metal-oxide ceramic film;
- placing the laser-light shield between a laser-light source and a human body;
- and
- directing the flame-sprayed metal-oxide ceramic film toward a source of the laser light.
