Abstract: A method for producing an optical device includes steps of: providing a first mold set, a second mold set, and an inner mold member cooperating with the first mold set to define a first molding cavity; filling a first plastic material into the first molding cavity so as to form a first molded object including a first molded element; placing the first molded object and the inner mold member into the second mold set to cooperatively define a second molding cavity; filling a second plastic material into the second molding cavity so as to form a second molded object including a second molded element; and disconnecting the first and second molded elements from the first and second molded objects.

Abstract: Mold apparatuses may comprise a mold body, a thermostat target area and a channel unit. Said thermostat target area may be defined in said mold body. The channel unit may comprise a thermostat channel which may be formed in said mold body and may be connected with the outside to maintain the temperature of said thermostat target area through the thermostat medium flowing through it, and a heat conductive partition disposed in the thermostat channel. Said thermostat channel may comprise a first channel located on one side of said heat conductive partition; a second channel located on the other side of said heat conductive partition; a first port connected with said first channel and the outside; a second port connected with said second channel and the outside; and a connect channel away from the first port and the second port and connected with said first channel and said second channel.

Abstract: An optical device includes a supporting frame and a light-transmissive element. The supporting frame has a frame body defining a through hole, and an extending portion extending from a side of the frame body and having a first cutting edge. The light-transmissible element is disposed on the supporting frame and has a main body aligned with the through hole, and an extending portion extending from a side of the main body and aligned with the extending portion of the supporting frame. The extending portion of the light-transmissible element has a second cutting edge that is flush with the first cutting edge of the supporting frame.

Abstract: The present invention provides an optical imaging lens. The optical imaging lens comprises a lens barrel and several lens elements positioned therein. Each lens element has a lens portion and a peripheral portion formed around the lens portion and extending to the rim. The lens portion is formed with an object-side surface facing to the object side and an image-side surface facing to the image side for passing the light. One of the lens elements is an embedded lens element. The radius from the center to the rim of the embedded lens element is smaller than that of another lens element adjacent to the embedded lens element and thus the rim of the embedded lens element is embedded in the peripheral portion of the adjacent lens element.
