  • Patent number: 11183810
    Abstract: In a light source module A, a lens shapes emitted light 1a of a semiconductor laser. A plate on which the lens is disposed has a through hole through which the emitted light of the semiconductor laser passes and an adjustment surface that is used for adjusting the position of the lens with respect to the through hole in a direction perpendicular to the optical axis L of the semiconductor laser. An end surface 5b of the lens that is opposite to an optical light-emitting surface of the lens is fixed to the adjustment surface with an adhesive AD. A stepped portion that is recessed in the direction of the optical axis L is formed in a bonding portion in which the end surface of the lens and the adjustment surface are bonded together.

  • Publication number: 20210144348
    Abstract: A projector apparatus includes a projection unit that projects an image on a projection target, a distance-measuring unit that measures a distance from an emitting end of the projection unit to the projection target, and a control unit that sets a luminance of projection light to a predetermined constant value when a distance measured by the distance-measuring unit is equal to or smaller than a predetermined distance and increases the luminance of the projection light such that the luminance does not exceed a set luminance of the projection light corresponding to the measured distance when the distance measured by the distance-measuring unit is larger than the predetermined distance.

  • Patent number: 10012843
    Abstract: A light beam separating and absorbing element includes a mirror that receives first and second light beams incident on a first surface, and the mirror is configured to transmit the first light beam and reflect the second light beam. A beam absorber receives the first light beam transmitted through the mirror, and absorbs a first light portion of the transmitted first light beam after the first light beam has been transmitted through the mirror. The beam absorber scatters a second portion of the first light beam, and the beam absorber and mirror are positioned such that at least a portion of the scattered light is incident on a second surface of the mirror. Transmissivity of the mirror for the scattered light incident on the second mirror surface may be lower as compared to transmissivity for the first light beam incident on the first mirror surface to enhance separation of the first and second light beams.
