  • Publication number: 20230375786
    Abstract: An optical member includes a light guide made of a transparent material. The light guide has: an incident surface; an exit surface having exit portions and flat portions; a smooth surface arranged opposite to the flat portions; an upper surface and a lower surface arranged opposite to each other so as to connect the smooth surface and the exit surface; a first protrusion protruding from the upper surface; and a second protrusion protruding from the lower surface. The flat portions reflect the incident light toward the smooth surface by total reflection. The smooth surface reflects the reflected light reflected by the flat portion toward the exit surface by total reflection. The exit portions emit a part of the incident light or a part of light reflected by the smooth surface to the outside.

  • Publication number: 20150221501
    Abstract: According to one embodiment, in an imprint method, a template in which a pattern is arranged in a central region and an outside region is contacted against a first imprint shot. Light is irradiated via a dimming member so that a partial region of a resist contacted by the outside region has hardness lower than target hardness, and thereafter, the template is separated. Furthermore, the template is contacted against a second imprint shot so that the first and second imprint shots are superposed in the partial region. Light is then irradiated so that the resist in the partial region reaches the target hardness, and thereafter, the template is separated.
