  • Patent number: 8796798
    Abstract: An imaging module includes an imaging chip including a micro-lens guiding incident light and an imaging element in a semiconductor substrate and converting the incident light into an electric signal, and a polarizing glass chip including a polarizing filter glass having a polarizer determining a polarization direction of the incident light arranged on a transparent substrate such that the polarizer faces the micro-lens and a spacer member connected to the polarizing filter glass to adjust a gap between the polarizer and the micro-lens of the imaging chip. In the imaging module, a melt-bonding surface of the spacer member is melt-bonded to the semiconductor substrate such that the polarizer of the polarizing glass chip and the micro-lens of the imaging chip are arranged close to each other via the gap, and the imaging element and the micro-lens of the imaging chip are sealed by the polarizing glass chip.

  • Patent number: 8120842
    Abstract: A wavelength conversion device enabling the stable output of high-power harmonic light is disclosed. The wavelength conversion device includes MgO:LiNbO3 (PPMgLN) having a periodic polarization reversed structure, and the +Z and ?Z surfaces of the PPMgLN are covered with thin chrome (Cr) film. In the PPMgLN, the incident surface and output surface are disposed on the ?X side and +X side, respectively, in the longitudinal direction. Because of this structure, even when a high-power laser fundamental wave is incident, the PPMgLN can avoid destruction and damage due to the electric field, thereby enabling the stable output of high-power harmonic.
