Abstract: An adjustable optical mount adapted for use with an optical table defining a reference plane includes a hollow housing with openings in the side walls to allow passage of an optical beam therethrough, a gimbal base fixed on the top of the housing, a gimbal plate adjustably mounted under the gimbal base, and a carrier bracket fixed to the gimbal plate for holding preselected optical elements within the housing along the path of the beam. Adjustment mechanisms are provided to tilt and rotate the gimbal plate so as to align the optical element on a selected axis relative to the reference plane.

Abstract: Apparatus and methods in which very small volumes of material may be extracted, delivered, interrogated or stimulated via optical, electromagnetic or mechanical means, in vivo or in vitro, for site-specific detection, characterization, stimulation, diagnostics or therapy, comprising optical, fluidic, chemical, electromagnetic and biological techniques applied via a microprobe in a single intra-parenchymal tissue perforation procedure in the brain. The primary use of the device is in neuroscience research, clinical diagnostics and therapeutics applications in the brain, however, the device may also be beneficially applied to other organs and biological systems. Human clinical applications may include neurosurgical intra-operative monitoring, extra-operative chronic monitoring of devices introduced in an operation, and diagnostic monitoring combined with simultaneous neuroimaging.
