Abstract: An optical device for viewing distant objects. The device includes an objective system and at least one ocular and achieves a magnifying power of greater than 0.6 mm?1 times the entrance pupil diameter in millimeters with an exit pupil of at least 2 mm Images from the objective system are detected by a sensor, processed and recorded. The images are displayed on a display which is observed by the user through one or more oculars. The optical device works well at low light levels. The device also has a slide mechanism for adjusting the interpupillary distance between the oculars.

Abstract: A tele wide module includes a first optics group, a fixed position for the first optics group, a second optics group, a set of predetermined positions for the second optics group, a selector for selecting a first position from the set of predetermined positions, and an image sensor. The first optics group is configured to provide a focus to the image sensor. The focus is based on the selected first position. A method of adjusting a lens configuration selects a first position from a set of positions. Based on the selected position, the method deposes a second lens group in relation to a first lens group. Typically, the position of the first lens group is fixed. Through the first and second lens groups, the method provides an image to an image sensor. The method of some embodiments provides a focused image to the image sensor by using a hyper focal setting.

Abstract: An optical module includes a first optics group, a second optics group, and an image sensor, wherein the first optics group and second optics group are configured to provide an image having a focus and a magnification to the image sensor. In some embodiments of the present invention, a first optics assembly includes a first optics group coupled to a threaded portion of a first lead screw so that translation of the first lead screw results in translation of the first optics group along an axis of the first lead screw, a first actuator for rotating the first lead screw; and a first sensing target configured to permit detection of rotation of the first lead screw.
