COMPACT CONCENTRATOR AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A compact concentrator and a manufacturing method thereof are provided to reduce a size by forming one optical path by equalizing the orientation of the light with signal wavelengths. CONSTITUTION: An optical cuvette(210) forms a first hole which passes through the center of the main body in an optical axial direction and a second hole on one side of the main body in a vertical direction to an optical axis and makes the cross section of a light emitting side incline to the cross section of the light incidence surface on the surface with the first hole. A first dichroic mirror(220) is bonded with the cross section of the incident side of the optical cuvette and coats the first surface with the dichroic film. A second dichroic mirror(230) is bonded with the cross section of the light emitting side of the optical cuvette and coats the first surface with the dichroic film.
