METHOD AND APPARATUS FOR MACRO-FOCUS

摘要

A device for arranging a distance between an optical element and an image sensor (100). The device (100) includes a housing (200) mechanically coupled to the optical element, a frame (400) mechanically coupled to the housing (200), the frame (400) having a first extension (404), and a base (300) movably coupled to the frame (400), the base having a sloped first channel (308) accommodating the first extension (404). the first channel (308) having a first stop point (606) and a second stop point (604), wherein the frame moves between the first stop point and the second stop point, which correspond to first and second distances between the optical element and the image sensor, respectively.
