  • Patent number: 10488671
    Abstract: If an optical path length of an optical system is reduced and a length of a laser light on an irradiation surface is increased, there occurs curvature of field which is a phenomenon that a convergent position deviates depending on an incident angle or incident position of a laser light with respect to a lens. To avoid this phenomenon, an optical element having a negative power such as a concave lens or a concave cylindrical lens is inserted to regulate the optical path length of the laser light and a convergent position is made coincident with a irradiation surface to form an image on the irradiation surface.

  • Patent number: 8885258
    Abstract: Provided is a stack-type lens array capable of preventing a lens from peeling off due to stress during dicing or vibration and impact when used. The stack-type lens array is formed by stacking and bonding two lens sheets in which micro lenses are arranged on a flat portion at predetermined intervals. Antireflection films are vapor-deposited on a convex surface and a concave surface of the lens and a light shielding film is vapor-deposited such that a circular opening is formed at the center of the concave surface. The opening serves as a diaphragm aperture of the lens. An exposed surface in which neither the antireflection film nor the light shielding film is vapor-deposited is provided outside the light shielding film between adjacent lenses. A dicing line is set at the center of the exposed surface. An adhesive layer is formed in a predetermined pattern on the exposed surface.

  • Patent number: 8824053
    Abstract: Two aperture members are disposed on each side of a lens array. In one aperture member, decreasingly tapered through holes having a cross sectional area that gradually decreases in a light incident direction and increasingly tapered through holes having a cross sectional area that gradually increases in the light incident direction are alternatively arranged. The other aperture member that is oppositely disposed with respect to the lens array has the same configuration. The center axes of the decreasingly tapered through holes and the center axes of the increasingly tapered through holes are coincident with each other. This enables to achieve an image forming optical element that has a large amount of light and less irregularity of the amount of light.
