The laser light sources (111 to 113) respectively output light of a different wavelength. The stacked wave plate (130) includes multiple wave plates (131 to 133) and induces a phase difference on polarization components of transmitted light. The polarization films (121 to 123) adjust the polarization direction of the light such that an angle between polarization directions of the light emitted by the laser light sources (111 to 113) and input to the stacked wave plate (130) becomes an angle that corrects an orientation angle difference that occurs at the stacked wave plate (130), consequent to differences in the wavelength of the light."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical device","description":"An optical device (100) includes laser light sources (111 to 113), polarization films (121 to 123), and a stacked wave plate (130).
