IMAGE SENSING OPTICAL SYSTEM

摘要

PURPOSE: An image sensing optical system is provided to improve reliability and to increase productivity while reducing a volume of the image sensing optical system by minimizing assembling tolerance of the image sensing optical system. CONSTITUTION: An image sensing optical system includes a substrate(100) formed with a recess region(102) having a predetermined depth. An image sensor is formed on the recess region of the substrate. The image sensor is bonded to the substrate(100) through a semiconductor manufacturing process. An infrared ray shielding filter(116) is provided between an object and the image sensor. A lens(112) is provided to refract light from the object to the image sensor. A supporting member(114) surrounds the image sensor in order to support the lens(112). A light limiting device is provided to limit light approaching the image sensor. The lens(112) is integrally formed with the supporting member(114).
