Abstract: In an optical instrument for spectroscopically measuring color and gloss of a sample surface, a fiber optic probe is provided wherein light is transmitted from a light source to the probe through a fiber optic bundle. The fiber optic bundle is arranged to illuminate a surface positioned over an aperture in the probe. Light diffusely reflected from the sample surface is transmitted by a second fiber optic bundle to a spectrophotometer. A small fiber bundle is arranged in the probe to irradiate the surface of the sample at an angle of 60 degrees and a second small fiber bundle is arranged to receive light from the first mentioned small fiber bundle after being specularly reflected from the surface. The second fiber optic bundle transmits the received light to a photodetector in the spectrophotometer to provide an indication of the gloss of the sample surface.
