Multiple flash unit with light-spreading protective shield |
摘要 |
A prismatic protective shield for each flash-lamp and reflector combination has arrays of parallel prisms in order to level the light distribution with a tendency to produce an intensity dip at the pattern center. Arrays of horizontal prisms occupy a central vertical stripe of the shield plane. Arrays of vertical prisms are at each side of the horizontal prisms.
