Apparatus for visibly or invisibly pointing cameras, telescopes, weapons and other devices in the dark, characterized by the use of optical means, the image of a light source is projected, both as a point of light on an object to aim, so that this point of light is on the optical or pointing axis of the device to be directed, as well as with other optical auxiliary means is produced from the same light source a limited luminous field concentric to the point of light for the general illumination of the object visa, where this bright field, in order to increase the contrast, is separated from the luminous field by a dark field produced by another optical auxiliary medium concentrically to the point of light, so that, even using relatively weak light sources, get a sufficient effect.
