1. A light beam detection system comprising:

  • an area sized to receive the light beam;

    a beam separator disposed in the area to separate a small portion of the light beam from a remainder of the light beam to provide a separated light beam and a remainder light beam and to transmit the separated light beam to a spectroscopy device;

    an imaging device disposed in the area to operably receive the remainder light beam to provide an image therefrom; and

    , a spectroscopy device optically connected to the beam separator to receive the separated light beam to provide a spectrum therefrom, wherein the beam separator is located substantially in front of and does not touch the imaging device and wherein the system further comprises a first focusing element in front of the beam separator and a second focusing element between the beam separator and the imaging device, the first focusing element and the second focusing element located to provide a first conjugate image plane substantially at the beam separator and a second conjugate image plane substantially at the imaging device.
