Stereotaxic Cannula Holders with angle adjustment

The Stereotaxic Cannula Holder with Angle Adjustment aligns the cannula angle with the Z-axis of the stereotaxic frame. This angle adjustment feature is particularly useful when the optical fiber is not parallel to the stereotaxis holder, either by design or due to manufacturing tolerance.
The main rod that is attached to the stereotaxic frame is 6.35 mm in diameter, and 79 mm long. If needed, the main rod can be replaced by one with a #8-32 internal thread size.
The adjustable angle component is compatible with most Doric stereotaxic cannula holders that have a 6.35 mm rod diameter.
