An improved adjustable light diffuser for selectively attenuating light passed through a film gate for removing high intensity "hot spots." The diffuser includes a support frame having taut, thin wires suspended therefrom in a "spider web" fashion. The light attenuators consist of one or more metallic screens which are suspended from the taut wires by having the wires pass through the screen orifices, thereby to provide a highly flexible system for readily positioning the screens at desired portions of the device. Both angular and translational adjustments may be readily accomplished in a highly economical manner.
