摘要

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 O.6mrn-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.
