Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: An optical lens includes a lens member and two shade layers on opposite sides of the lens member. The lens member respectively has a lens portion on each side thereof. Each shade layer has an aperture above the corresponding lens portion of the lens member to serve the function of aperture. A method uses optical lithography technique to make such optical lens in a fast way, and the shade layers will have a strong bonding strength with the lens member.

Abstract: A method of making lens modules includes the following steps: Put a plurality of lens members between a first die and a second die, wherein the first die touches the substrate of each lens module, and the second die touches the lens of each lens module. Provide a housing material between the first die and the second die, and then solidify the housing material. Remove the first die and the second die to obtain a block; and Cut the block to obtain a plurality of lens modules.

Abstract: An optical lens assembly includes a first lens, an adhesive layer, and a second lens in sequence, wherein the first and the second lenses are rectangular in shape. The adhesive layer is made of an adhesive acrylic composition. to adhere both sides thereof to interior sides of the first lens and the second lens, and the adhesive layer has following conditions: a transmittance greater than 70%; |n3?n1 |<0.5; and |n3?n2 |<0.5; where n1 is a refractive index of the first lens; n2 is a refractive index of the second lens; and n3 is a refractive index of the adhesive layer.

Abstract: A method of making lenses includes the following steps: A. Provide a photo-curing material into a cavity between a first die and a second die. B. Expose the photo-curing material under predetermined light, whereby the photo-curing material is solidified, and a transmittance of the solidified photo-curing material is greater than 75%. C. Remove the first die and the second die to obtain a lens material; and D. Cut the lens material to obtain a plurality of lenses.

Abstract: A combination lens includes a first lens having a first lens portion on a side thereof and at least a protrusion around the first lens portion, and a second lens having a second lens portion on a side thereof and at least a recess around the second lens portion. The first lens is bonded to the second lens by engaging the protrusion with the recess. Therefore, the engagement of the protrusion and the recess may fix the first and the second lenses in a right position before the glue solidified.

Abstract: This invention relates to a composite antenna used in a radio transceiver, which comprises a first antenna and a detachable antenna set. The first antenna can be used without the detachable antenna set for transmitting and receiving radio signals radiated from the radio transceiver. The detachable antenna set comprises a second antenna for transmitting and receiving radio signals and an antenna sheath electrically connected to the second antenna, for detachably attaching to the first antenna. When the antenna sheath is attached to the first antenna and electrically connected to the signal line and the ground port therein, radio signals transmitted or received by the radio transceiver are confined within the antenna sheath and can be transmitted or received through the second antenna of the detachable antenna set.
