Abstract
An array refracting element for dividing laser beams in a sub-scanning direction, which is formed by linearly disposing a pair of refracting members, each having a unit surface shape for dividing one incident laser beam into two and emitting the divided laser beams, so that directions in which the laser beams are divided are coincident with each other and so that the refracting members locate along the division direction, is disposed on an optical path of the laser beams emitted from plural semiconductor lasers, and between a laser-beam outgoing opening of a fiber array section and a recording film. As a result, an array refracting element and an exposure device, which can improve quality of a recording image at an exposure recording apparatus at a low cost, can be obtained.
