  • Patent number: 8731019
    Abstract: [Objective] To restrict degradation of optical characteristics due to a resin adhesive containing an inorganic filler. [Means] The width d of a lens body 31 and the height of an inorganic filler 341 in a direction orthogonal to the surface of a substrate are set such that an inclination angle of a collimating lens 3 does not exceed a maximum tolerable inclination angle when the inorganic filler 341 is positioned near the width-wise center of the lens body 31. As a result, even when the inorganic filler 341 is inserted between the bottom surface of the collimating lens 3 and the top surface of the substrate 4, degradation of the optical characteristics of the laser module including skewing of the optical axis of the laser light and distortion of the beam shape of the laser light can be restricted.

  • Publication number: 20120127715
    Abstract: [Objective] To prevent change in a direction of an optical axis of a split light within a plane parallel to a surface on which the beam splitter is installed. [Means] A laser module including a laser light source that emits a laser light and a beam splitter that splits a portion of the laser light emitted from the laser light source. The beam splitter includes a first reflective surface and a second reflective surface that are parallel to each other. The first reflective surface transmits a first portion of the laser light and reflects a second portion of the laser light to the second reflective surface. The second reflective surface receives the second portion of the laser light from the first reflective surface and reflects received laser light in a direction parallel to the laser light emitted from the laser light source.
