PROBLEM TO BE SOLVED: To provide an array type optical component and an optical system for an array type semiconductor laser, wherein the output light from an array type semiconductor laser is converted to an isotropic condensing light beam through a relatively simple arrangement. SOLUTION: The array type optical component 3 is constituted by stacking a plurality of triangular prismatic unit transmission optical elements each having a light incident face 3a for receiving the output light from the array type semiconductor laser 1, a light-reflecting face 3b for reflecting the light refracted on the light incident face 3a and a light exit face 3c for refracting the light reflected on the light-reflecting face 3b such that the light-reflecting faces 3b are substantially parallel. Assuming that an arranging direction of light-emitting points of the array type semiconductor laser 1 is a X direction, a traveling direction of the output light is a Z direction and a direction perpendicular to the X direction and the Z direction is a Y direction, the light-reflecting face 3b of each unit transmission optical element is arranged to be in parallel to the Z direction and to intersect a X-Z plane at substantially 45°.
