ABSTRACT:
An optical system comprising a cavity for spectrophotometric measurements and the like with a first cylindrical refraction index gradient lens matched to an optical fiber. A second cylindrical refraction index gradient lens is provided disposed approximately coaxial to the first lens. The first and second lenses are spaced apart to delimit the cavity between opposite faces of the first and second lenses. A sample under test is positioned within the cavity. A reflecting surface is provided on the face of the second lens opposite said cavity.
