Uniformity as it impacts imaging ex vivo specimens from large imaging distances. Image a was captured of the sectioned specimen using the FL device and d using the WL device. In b and e, the uniformity contours from Fig. 5f were overlaid on (a) and (d) respectively. The outline of the maximum uniformity contour was traced by the yellow line. The contours were then removed from (b) and (e) to produce (c) and (f) respectively, leaving the traced maximum uniformity contour. A small piece of tissue outside of this contour, visible in (f) as indicated by the white arrow, is not obvious in (c)
