Abstract

A multi-functional photometer includes a scanning mechanism having a housing that bears a movable linkage. The linkage is coupled to an optical scanning head and incorporates light-transmitting paths with at least one reflective surface for transmitting radiant energy to and from the scanning head. The arm comprises a C-shaped elbow member, pivotally attached to a shoulder member. In turn, the shoulder member of the arm is pivotally connected to the housing. In one embodiment the reflective surfaces are optically coupled and are mounted onto the housing, shoulder member and elbow member, such that the shapes of the light-transmitting paths remain fixed regardless of the orientation of the arm. The housing further incorporates a Cartesian-coordinate table for positioning the scanning head with respect to a microplate that contains a plurality of analyte samples.
