Abstract: A process comprises projecting a radiation beam (213) from a movable optical element (202) onto an image sensor positioned along an optical axis (210) of the movable optical element (202) and substantially normal thereto. The movable optical element (202) is movable relative to the image sensor (222) and the radiation beam is projected at a selected angle relative to the optical axis. A plurality of targets are positioned at known front focus distances from the movable optical element, and for each front focus distance, a back focal length of the movable optical element and the position where the beam of radiation falls on the image sensor are recorded.

Abstract: An apparatus comprising a movable optical element having an optical axis and including one or more focusing elements, an image sensor positioned along the optical axis and substantially normal thereto, and a radiation source attached to the movable optical element, wherein the radiation source directs a beam of radiation onto the sensor at a selected angle relative to the optical axis. A process comprising positioning a sensor along, and normal to, an optical axis of a movable optical element, projecting a radiation beam onto the sensor from a radiation source attached to the movable optical element, wherein the radiation beam is at a selected angle relative to the optical axis, and adjusting the position of the movable optical element until the position where the radiation beam falls on the sensor corresponds to the position where the radiation beam is expected to fall on the sensor when the movable optical element is in focus. Other embodiments are disclosed and claimed.
