1. A spectrometer probe comprising:
a shaft having an outer sleeve having a first end and a second end;
an endcap attached to the first end of the outer sleeve;
a spacer tab;
a probe sample window;
a light reflection insert, wherein the light reflection insert is attached between the probe sample window and the first end of the outer sleeve, wherein the spacer tab is connected between the probe sample window and the end cap;
a top spacer tab attached to the second end of the outer sleeve;
a protector tube top cap attached the top spacer tub at the second end of the outer sleeve;
a near-infrared probe cable connected to the protector tube top cap, wherein the near-infrared probe has a first end and a second end;
a read fiberoptic cable connected at the second end of the near-infrared probe;
a light source fiberoptic cable connected at the second end of the near-infrared probe;
a fiber bundle located within the outer sleeve, the fiber bundle having a first end and a second end, the read fiberoptic cable and the light source fiberoptic cable combine to form the fiber bundle;
a concave mirror or a sapphire prism;
a backscatter baffle;
a sapphire window;
set screws;
an inner sleeve;
a spring;
an index-matching elastomer; and
a penetration cone operatively attached to the second end of the near-infrared probe, the index-matching elastomer attached to the second end of the fiber bundle, wherein the sapphire window is substantially parallel with the fiber bundle and the outer sleeve, wherein the backscatter baffle is attached parallel to the fiber bundle, wherein the backscatter baffle has a first end and a second end, wherein the second end of the backscatter baffle extends beyond the second end of the fiber bundle, wherein the penetration cone is operatively connected to outer sleeve via an inner sleeve, wherein the inner sleeve is connected to the outer sleeve by set screws.
