1. An apparatus for a spectral analysis, comprising:
a first lens holder comprising a first lens;
a second lens holder comprising a second lens, wherein the first lens and the second lens are configured to receive and focus a scattered light beam;
a first optical fiber arranged between the first lens holder and the second lens holder, the first optical fiber configured to receive a first light beam focused by the first lens, transmit the first light beam through and project the first light beam onto the second lens; and
a spectrometer positioned on a side of the second lens holder opposite the first optical fiber, wherein the second lens focuses the first light beam received from the first optical fiber and projects the first light beam onto the spectrometer, so that the spectrometer can analyze the first light beam.
