Abstract
A targeting system for a spectrophotometer includes a plurality of fiber channels, including at least one measurement channel and at least one illumination channel. A slit assembly includes a translucent layer disposed adjacent the plurality of fiber channels, and reflective portion disposed adjacent the translucent layer. Each fiber channel includes a first end, the first end offset from the reflective portion of the slit assembly to allow light transfer from one fiber channel to an adjacent fiber channel. A light source is in optical communication with the at least one illumination channel. A sample plane is in optical communication with a second end of the measurement channel. The system is configured such that light is transmitted from the light source, through the at least one illumination channel, reflected off the slit assembly, transmitted through the measurement channel, and onto the sample plane.
