Fig. 10.

Image of the stray light assembly used during stand-alone calibration. A broadband source is coupled to a $2^{″}$ diameter collimator by an optical fiber. Dovetail rails are mounted on rotation stages that allow for 3-dimensional positioning of the collimator with respect to the camera boresight. Shown here is the collimator at a position of $-{20}^{\circ }$ in azimuth and $-0^{\circ }$ elevation
