Off-Axis Illumination

Edge 5x Side Light 1

Off axis lighting with a fiber optic illuminator provides excellent contrast while also allowing some of the subject’s topography to remain hidden.  Quite often, changing the direction of illumination offers dramatic changes in the view. This is an excellent lighting technique but, if it is to be effective - care must be taken.

Simply plopping down a light in one position and expecting to see everything that needs to be seen may result in drawing a conclusion from insufficient data.
