1. An optical emission spectrometer system, comprising:

  • a light source configured to emit first light in a first direction and second light in a second direction different from the first direction;

    a dichroic beam combiner configured to receive the first light via a first light path and the second light via a second light path, to reflect a portion of the first light into an entrance aperture of a light detection and measurement apparatus, and to transmit a portion of the second light into the entrance aperture, wherein the portion of the first light reflected into the entrance aperture predominately has wavelengths in a first range of wavelengths and the portion of the second light transmitted into the entrance aperture predominately has wavelengths in a second range of wavelengths different from the first range of wavelengths; and

    a movable member including the dichroic beam combiner, a mirrored section and a transparent section, the movable member being operable to place one of the dichroic beam combiner, the mirrored section and the transparent section into the first and second light paths for receiving the first and second light.
