Diffuser (optics)

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.
