TRANSDUCER SYSTEM FOR AN OPTICAL SENSOR BASED ON SURFACE PLASMON RESONANCE

摘要

Device for the surface plasmons resonance measurement surfaces with an at least a cuvette (32) cuvettes comprising unit (30) and with a transducer prism (10), the opposing side surfaces (14) for the entry or the exit of light rays as well as one of the cuvettes unit (30) associated with the bottom of upper side with an applied layer (12) of a free electrons metal, characterized in that the cuvettes unit (30) and the transducer prism (10) are designed as a separate exchangeable components that the or each cuvette (32) is tubular in design and at the lower end of the tube a circumferential sealing edge (34) for abutment on the upper side of the transducer prism (10), and in that a retaining device (20) for receiving the trasducerprismas (10) and of the cuvettes unit (30) are sealed off from one another in their operating position is provided.
