摘要： An apparatus is described in which an optical fiber is mounted within a fiber optic holder which includes the non-rotating shaft of a linear actuator. The fiber holder may be held captive in order to restrain the fiber holder and, consequently, the fiber mounted therein, from rotating during operation of the linear actuator, thereby resulting in linear travel with minimal rotational effects and minimal change in optical alignment of the fiber during travel. In addition, an optical path length sensor in conjunction with an optimize dabsorbance method of operation is utilized herein to provide micron precision of the displacement between respective receiving and transmission fibers so as to enable precise absorbance measurements from about 0.005 up to about 2.0 Absorbance Units for any given path length.
