Patent number: 11947090Abstract: A lens module includes a plurality of lenses, an annular body and a reflective element. The reflective element, the lenses and the annular are sequentially arranged along an optical axis from an object side to an image side. The lenses include a first lens that is disposed closest to the object side, and a second lens that is disposed closest to the image side. The reflective element is disposed between the object side and the first lens. The annular body is disposed between the object side and the first lens, between the lenses, or between the second lens and the image side. The lens module satisfies 0.5 mm<EPA/PL<5.5 mm where EPA is an area of an entrance pupil of the lens module, and PL is a length of the reflective element.Type: GrantFiled: January 3, 2022Date of Patent: April 2, 2024Assignees: SINTAI OPTICAL (SHENZHEN) CO., LTD., ASIA OPTICAL CO., INC.Inventors: Chun-Yu Hsueh, Tsung-Tse Chen, Chun-Hung Huang

Publication number: 20230228964Abstract: A lens device includes a lens group unit, a guiding unit, a transmission unit and a driving unit. The guiding unit is connected to the lens group unit for guiding the lens group unit to move in a first direction or in a second direction. The transmission unit includes a fixing element. The driving unit is connected to the transmission unit so as to output power for driving the lens group unit through the transmission unit to move in the first direction X or in the second direction. The fixing element includes a body portion and a bent portion, and the bent portion extends from the body portion to form a space between the fixing element and the lens group unit.Type: ApplicationFiled: December 6, 2022Publication date: July 20, 2023Inventors: Chun-Yu Hsueh, Chun-Hung Huang, Tsung-Tse Chen, Duen-Kwei Hwang

Publication number: 20220146717Abstract: The present application provides an aperture assembly. The aperture assembly is used in an optical lens system. The aperture assembly includes a plate including a hollow portion and a non-hollow portion. The hollow portion is configured to define an aperture of the optical lens system, wherein the contour of the hollow portion has a non-circular shape. The aperture assembly can prevent the size of the aperture from being reduced as the size of the plate is reduced in a case that a circular aperture is applied to the plate. The present application also realizes an aperture adjustment for a non-circular aperture.Type: ApplicationFiled: October 24, 2021Publication date: May 12, 2022Inventors: Chun-hung HUANG, Tsung-tse CHEN

Patent number: 9250412Abstract: A lens device includes a first barrel surrounding an optical axis, a first frame coupled rotatably to the first barrel and surrounding a first axis, and an adjusting unit. The adjusting unit has an adjusting groove formed in one of the first barrel and the first frame, and having adjusting groove segments, one of which extends spirally. The adjusting unit further has adjusting blocks formed on the other one of the first barrel and the first frame and engaging respectively and slidably the adjusting grooves. The first frame is rotatable relative to the first barrel to adjust the first axis relative to the optical axis.Type: GrantFiled: April 19, 2013Date of Patent: February 2, 2016Assignees: Sintai Optical (Shenzhen) Co., Ltd., Asia Optical International, Ltd.Inventor: Tsung-Tse Chen

Patent number: 8976290Abstract: A positionable mechanism includes a base unit, a frame unit, an optical image stabilizing (OIS) unit and a positioning unit. The frame unit and the OIS unit are mounted on the base unit. The frame unit is retractable with respect to the base unit between a storage position and a working position, and has a first surface. The OIS unit includes a movable carrier that has a second surface facing the first surface, an optical element that is mounted on the movable carrier, and a driving element that is operable to drive the movable carrier to move with respect to the base unit. The positioning unit is disposed between the first surface and the second surface, and is configured to position the movable carrier with respect to the frame unit when the frame unit is at the storage position.Type: GrantFiled: September 12, 2012Date of Patent: March 10, 2015Assignee: Asia Optical International Ltd.Inventors: Tsung-Tse Chen, Chia-Lin Hung, Huo-Wang Chou

Patent number: 8665362Abstract: A positionable mechanism includes a frame unit, an OIS unit, and a positioning unit that are mounted on a base unit. The frame unit is retractable with respect to the base unit between a storage position and a working position. The positioning unit is movable with respect to the OIS unit between an abutting position and a releasing position, and is subjected to a restoring force. When the frame unit is at the storage position, a pressing part of the frame unit presses the positioning unit to the abutting position where the positioning unit abuts against a movable carrier of the OIS unit. When the frame unit is at the working position, the positioning unit is restored to the releasing position and releases the movable carrier.Type: GrantFiled: September 12, 2012Date of Patent: March 4, 2014Assignee: Asia Optical International, Ltd.Inventors: Chun-Yu Hsueh, Tsung-Tse Chen
