Provided is a system for characterizing biological/chemical test specimens. In particular, a container such as a tube or capillary for containing a test specimen is interconnected at one end to a light source via a fiber optic. A second end of the tube is connected to a detector via a second fiber optic. In one embodiment, the containing tube exhibits "total internal reflection". As light is projected into the tube, one or more electric fields are applied to the specimen. Light travels the length of the tube to excite specimen molecules, which subsequently emit light having a wavelength longer than that of the projected light. The emitted light travels the length of the tube, is detected, and is then transmitted to a processor for analysis. In an alternate embodiment, the tube is not TIR therefore emitted light exits the tube along its length, wherein it is detected by one or more detectors.
