OPTICAL SYSTEM FOR TAKING OVER THE IMAGE FROM A SIGHTING TELESCOPE

摘要

The invention relates to an optical system included in an optical device for taking over the image from a sighting telescope, said optical system being attached to the eye-piece thereof, having the role of picking up the image formed by means of the telescope and of remotely transmitting it, allowing, at the same time, the direct observation through the sighting telescope. According to the invention, the optical system is formed of a dividing blade (2), an element (3) for deviating the optical axis at an angle of 90°, which may be a prism or a mirror and an objective (4) focussing the images formed through a sighting telescope (1) on an optical sensor (5) of a video-camera (6), the objective (4) including a positive frontal lens (L1) and a negative doublet (D1), a second positive or negative doublet (D2) and a positive lens (L2).
