Abstract: A support arrangement positions an optical system in a generally vertical plane. The support arrangement may include an optical support panel that can be arranged in an upright position. At least one mounting surface of the optical support panel may be arranged vertically so that its entire surface area is within an arms-length distance or freely accessible to a standing or seated user. An unobstructed zone may be defined immediately adjacent to the mounting surface(s), which is substantially devoid of any supporting or other structures as mechanical barriers to the vertical mounting surface(s). The optical support panel may be rotationally and/or height adjustably mounted within a frame. A control system may facilitate remote height and/or angular position adjustments of the optical support panel.

Abstract: This invention provides methods and devices for identifying and/or characterizing interactions involving molecules, including, but not limited to, identifying and/or characterizing interactions involving target molecules and candidate molecules. The present invention provides methods using multidimensional infrared spectrographic techniques, such as four wave mixing and pump-probe techniques, for identifying interactions involving biomolecules and therapeutic candidate molecules, and for characterizing such interactions in terms of their binding coefficients and/or equilibrium constants.
