Abstract: An optical device includes a structured light generation unit and a beam splitter assembly. The structured light generation unit generates a structured light. The beam splitter assembly is arranged in a travelling path of the structured light. The beam splitter assembly includes a semi-transmissive semi-reflective structure. A portion of the structured light is transmitted through the semi-transmissive semi-reflective structure of the beam splitter assembly and projected on a projection surface. Consequently, a first structured light pattern is formed on the projection surface. Another portion of the structured light is reflected by the semi-transmissive semi-reflective structure of the beam splitter assembly and projected on the projection surface along a different path. Consequently, a second structured light pattern different from the first structured light pattern is formed on the projection surface. The number of structured light patterns or the projected area is correspondingly adjusted.

When a structured light from the structured light generation unit is projected on a test surface, a test pattern and a test light spot are shown on the test surface.

The detecting method judges whether a test surface is flat and detect a distance of the test surface. Since the structured light is used to detect the distance and the flatness of the test surface, the measuring complexity is reduced.

Abstract: An injection mold and an optical lens produced from the injection mold are provided. The injection mold includes a disk-type mold base and a nozzle. A mold cavity chamber is defined by the disk-type mold base. The mold cavity chamber includes an optically effective central runner and an optically ineffective annular runner. Moreover, plural spoiler structures are formed in the optically ineffective annular runner. While a melt is injected from the nozzle to the mold cavity chamber, the plural spoiler structures provide the functions of disturbing the melt flow and decreasing the velocity of the melt in the optically ineffective annular runner. Consequently, before the optically ineffective annular runner is completely filled with the melt, the optically effective central runner is completely filled with the melt. Since no defect is formed in an optically effective zone, the yield of the optical lens is enhanced.

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.
