Abstract:
An optical splitter includes a housing, a diffraction grating, and an optical filter. An incidence unit and an emission unit are provided in the housing. The optical filter is disposed between the emission unit and the diffraction grating in the housing. An anti-reflection coating is formed on a surface of a filter main body of the optical filter on the emission unit side. Therefore, from light dispersed by the diffraction grating and having passed through the optical filter, light reflected at a back surface of the emission unit passes through the optical filter without being reflected by a back surface of the optical filter and is directed toward the inside of the housing. As a result, light having passed through the optical filter and having a wavelength other than a target wavelength is inhibited from being emitted from an emission slit of the emission unit.

Claim (Index 1):
An optical splitter comprising:\n a housing into which light is incident and which emits the incident light from an emission slit; a diffraction grating provided in the housing and configured to disperse the light incident into the housing into light by wavelength; and an optical filter provided between the diffraction grating and the emission slit and configured to transmit only light of a selected wavelength to emit the light from the emission slit, wherein an anti-reflection coating is formed on a surface of the optical filter at least on the emission slit side.
