Patent number: 11815700Abstract: An optical lens assembly is produced by an injection-compression molding process. The optical lens assembly includes a lens body and an injection-molded structure. The lens body includes a first lens surface and a second lens surface opposed to the first lens surface. The lens body is divided into an optically effective zone and an optically ineffective zone. The injection-molded structure has at least one gate land in response to the injection-compression molding process. At least a portion of the optically ineffective zone of the lens body is covered by the injection-molded structure, and the injection-molded structure is assembled with and positioned by an external structure. Each of the first lens surface and the second lens surface is one of a multi-aperture lens surface, a lenticular lens surface, an aspheric lens surface, a flat lens surface and a freeform lens surface.Type: GrantFiled: August 14, 2020Date of Patent: November 14, 2023Assignee: EVERREADY PRECISION IND.

Publication number: 20210191143Abstract: A structured light generation device includes a laser light source module and a diffractive optical element. After a non-collimated light beam from the laser light source module is received by a diffraction layer of the diffractive optical element, the non-collimated light beam is modulated as an optical information-bearing light. Since no collimator is between the laser light source module and the diffractive optical element, the spacing distance between the laser light source module and the diffractive optical element is shortened. Consequently, the overall structured light generation device is slim.Type: ApplicationFiled: December 11, 2020Publication date: June 24, 2021Inventors: JYH-LONG CHERN, CHIH-MING YEN

Publication number: 20200173912Abstract: An optical device includes a door, a door control unit, a polarized light generation unit and a spectrum response analysis unit. The polarized light generation unit and the spectrum response analysis unit are located at a first side of the door. When the door is opened by the door control unit, a polarized light from the polarized light generation unit is transmitted through the door and externally projected on an under-test object at a second side of the door, so that a scattered light is generated. After the scattered light is returned back and transmitted through the door, the scattered light is projected on the spectrum response analysis unit, so that the spectrum response analysis unit performs a spectrum response analysis. The optical device has enhanced signal-to-noise ratio. Moreover, the optical device is capable of acquiring more explicit and diverse inherent information of the under-test object.Type: ApplicationFiled: February 11, 2020Publication date: June 4, 2020Inventors: Jyh-Long CHERN, Chih-Ming YEN
