In
case of diffused lighting, the control of the lighting angle is not
do-able like variable lighting
angle adapter but soft light which is diffused in every direction
is available. This is especially effective for the reduction of harsh
reflection on shiny metal surfaces.
Diffused light travels in various directions, hitting the observed
sample in a balanced dispersion of light to reduce the effect of intense
reflection. Consequently diffused lighting offers a good solution
for many difficult reflective samples.
