IRRAS accessory currently in use at Rutgers University. The Wilhemy plate is placed on the right hand side of the trough. The reference channel is to the left of the barrier. The entire trough shuttles as indicated to sample the desired channel. The incident light is guided to the surface via three mirrors. The beam path is represented as a dashed line. The reflected light follows an equivalent optical path. The angles of incidence and reflection as well as the state of polarization are under computer control.
