Abstract: An optical lens assembly is produced by an injection 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 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 and a flat lens surface.

Abstract: An optical apparatus includes plural optical lens groups with a specified field of view and an optical sensor accommodated and fixed within a casing. After a light beam passes through any of the plural optical lens groups, its travelling direction is changed, and it is sensed by the optical sensor and converted into an image signal by the optical sensor. The optical apparatus has a single optical lens module of minimized volume and is able to implement different optical functions simultaneously. Consequently, the fabricating cost of the optical apparatus is reduced, the assembling process is simplified, and the number of components to be assembled is reduced.

Abstract: An optical lens includes a substrate, at least one derivative structure and a diffractive optical structure. The substrate has an optically operable region and a derivatively operable region. The derivatively operable region is arranged around the optically operable region. The derivative structure is disposed on the derivatively operable region to increase structural strength of the optical lens and to reduce the stray light as being assembled in a module. The diffractive optical structure is disposed on the optically operable region, and includes a microstructure pattern for generating a structured light and/or correcting the optical defects. Consequently, the optical lens is suitable for miniaturization and assembling applications to a module.

Abstract: A method for scaling a structured light pattern and an optical device using the method are provided. The optical device includes a structured light generation unit and a conversion lens module. The conversion lens module is arranged between the structured light generation unit and a projection surface. The structured light generation unit outputs a structured light. After plural light beams of the structured light pass through the conversion lens module, the plural light beams are projected on the projection surface, so that a structured light pattern is formed on the projection surface. By controlling the conversion lens module to change traveling directions of the light beams of the structured light, the structured light pattern on the projection surface is correspondingly enlarged or shrunken.

Abstract: An optical apparatus includes a photosensitive element, a lens and a microstructure unit. The microstructure unit is arranged between the photosensitive element and the lens. After plural light beams passing through the lens are received by the microstructure unit, travelling directions of the plural light beams are changed. Consequently, at least a portion of the plural light beams is guided to the photosensitive element. In such way, the light collecting efficacy of the photosensitive element is enhanced.

Abstract: 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.

Abstract: An optical apparatus includes a structured light generation unit, a conversion lens module, a collimating lens and a casing. The structured light generation unit outputs a structured light. The light beams from the structured light generation unit are expanded by the conversion lens module. The expanded light beams are collimated by the collimating lens. After the light beams pass through the conversion lens module and the collimating lens, the light beams are projected to a projection surface. Consequently, a structured light pattern is formed on the projection surface. All conversion lenses of the conversion lens module have negative optical power. Consequently, the area of the structured light pattern on the projection surface is wider. Moreover, the structured light generation unit and the conversion lens module can be accommodated within the casing having a smaller thickness.
