Abstract: An optical element includes a lens component and a filter. The lens component has first, second, third, fourth, fifth, sixth and seventh surfaces disposed around and parallel to a reference axis. The lens component further has spaced apart first and second collimating units formed on the first surface, and a third collimating unit formed on the second surface. The second collimating unit is located between the first and third collimating units. The third surface is formed with a groove defined by the fourth, fifth, sixth and seventh surfaces. The filter is disposed on the third surface, covers the groove, and has a first side surface facing the fourth, fifth, sixth and seventh surfaces, and a second side surface opposite to the first side surface.

Abstract: An optical element includes a lens component and a filter. The lens component has a first plane, a second plane, a third plane, a fourth plane, a fifth plane, a first collimating unit formed on the first plane, a second collimating unit formed on the first plane, and a third collimating unit formed on the third plane. The first, second, third, fourth and fifth planes are disposed around and parallel to a reference axis. The third plane is formed with a groove defined by a sixth plane and a seventh plane which extend obliquely from the third plane and respectively opposite to the first and second planes. Each of the sixth and seventh planes extends in a direction that is parallel to the reference axis. The filter is disposed on the third plane for covering the groove.

Abstract: A lens assembly is used in a fiber-optic communication system, and includes a substrate and at least one lens unit formed on the substrate. The lens unit has first and second surfaces, a first light-transmissive region proximate to the first surface, a second light-transmissive region proximate to the second surface, a light attenuation region located between the first and second light-transmissive regions, and an optical axis passing through the first and second light-transmissive regions and the light attenuation region. The light attenuation region has at least one attenuation layer formed with multiple carbonized spots using a high-energy beam such that the light transmittance of the lens unit is not greater than 70%.

Abstract: An optical element includes a lens component and a reflecting mirror. The lens component includes first, second and third planes disposed to surround and parallel to a reference axis. The first plane is formed with first, second, third, and fourth collimating units. The second plane is formed with fifth and sixth collimating units. The lens component further includes fourth, fifth, sixth and seventh planes cooperatively defining a groove unit extending along and indented toward the reference axis from the third plane. The fourth and sixth planes extend obliquely relative to said first plane. The reflecting mirror is disposed on the third plane to cover the groove unit and has at least one reflecting plane facing the fourth, fifth, sixth and seventh planes.

Abstract: An optical element with light-splitting function includes a lens component and a reflecting mirror. The lens component includes first, second and third planes disposed to surround and parallel to a reference axis. The first plane is formed with a first collimating unit and a second collimating unit that is spaced apart from the first collimating unit. The second plane is formed with a third collimating unit. The third plane is formed with a groove extending along and indented toward the reference axis. The groove is defined by a fourth plane and a fifth plane. The fourth plane extends obliquely relative to the first plane. The reflecting mirror is disposed on the third plane to cover the groove and has a reflecting plane facing the fourth and fifth planes.

Abstract: A method of making a lens array plate with an aperture mask layer includes: preparing a lens substrate which is made from a plastic material and which has a plurality of spaced apart clear aperture regions for passage of light therethrough, and a mask-forming region which surrounds the clear aperture regions; and carbonizing the plastic material at the mask-forming region so as to form a carbonized aperture mask layer at the mask-forming region that can block ambient light from passing therethrough.

Abstract: An image-capturing device configured for a handheld electronic device includes a protective case and an image-capturing module having a first transmission unit. The protective case has a receiving space and an opening. The image-capturing module is disposed in the protective case, and includes a camera unit, a processing unit, and a second transmission unit. In response to user commands inputted through the handheld electronic device and communicated to the image-capturing device via the communication established between the first transmission unit and the second transmission unit, the processing unit is operable to control operation of the camera unit.

Abstract: A lens array module includes an arrayed optical element including a light blocking frame and a lens unit, and a light sensor array unit. The light blocking frame includes a bottom plate with multiple through holes, a surrounding wall, and a partition wall integrally connected to and cooperating with the bottom plate and surrounding walls to define multiple optical channels. The lens unit includes a substrate abutting against the bottom plate and including multiple lens elements that are aligned respectively with the through holes, and a plurality of upper positioning walls integrally connected to the substrate. The light sensor array unit includes multiple light sensing components respectively aligned with the lens elements.

Abstract: A method for fabricating an arrayed optical element includes: forming a light blocking frame using a first material that has a heat deflection temperature; placing the light blocking frame into a cavity of a mold; and injecting a second material into the mold to form a lens unit that is integrally connected to the light blocking frame, the second material being an optical plastic material and having a forming temperature lower than the heat deflection temperature of the first material.
