A system for delivering more than one optical power form and at least one control signal over an optical conduit includes control circuitry for controlling characteristics of the optical power system. Copies of this patent with color drawings will be provided by the Patent and Trademark Office upon request and payment of the necessary fee. The slope forms a space between the slope and a mounting surface on which the housing is placed. The fixed band provides an RF current path close to the RF coil window, while the movable band allows tuning the coil capacitance and resonance frequency by varying the area of overlap between the movable band and the central coil structure. The flow cell body has a lens provided on a surface thereof so as to traverse an optical path of the laser beam. Additionally, the assembly component includes a component locking member.
