In optics, a
diffuser is any device that or spreads out or scatters light in some manner, to give
soft light. Diffuse light can be easily obtained by making light to
reflect diffusely from a white surface, while more compact optical diffusers may use translucent objects, and can include
ground glass diffusers,
teflon diffusers, holographic diffusers,
opal glass diffusers, and greyed glass diffusers.
