Abstract
An optical waveguide for a magneto-optical current sensor. The optical waveguide includes a first end surface, through which light can be coupled into the optical waveguide, and a second end surface, through which light can be coupled out of the optical waveguide, wherein at least one of the two end surfaces has an anti-reflective coating.
Claims16
A magnetooptical current sensor for detecting an amperage of an electrical current in a current conductor, the current sensor comprising:
- at least one optical waveguide adapted to be arranged in an area of the current conductor, the optical waveguide comprising:
- a first end face, through which light can be coupled into the optical waveguide, and
- a second end face, through which light can be decoupled from the optical waveguide,
- wherein at least one of the first or second end faces has an antireflective coating and is an end face of a ferrule of a fiber-optic optical waveguide,
- wherein the optical waveguide is designed at least in sections as a fiber-optic optical waveguide.
