Surface plasmon resonance spectrometer with an actuator driven angle scanning mechanism

摘要

Instruments and methods relating to surface plasmon imaging are described. An instrument comprises a semi-circular rail and a driving mechanism. The driving mechanism is attached to a light source mount and a detector mount, and both the light source mount and the detector mount are attached to the semi-circular rail with connectors. Each connector allows the light source mount and detector mount to slide along the rail. The synchronous movement of the light source mount and the detector mount changes the angle of incidence of a light beam from the light source with respect to the plane of the sample surface on the sample stage.
