Abstract:
An arrangement in which light is directed onto a surface proceeding from a light source by first optics, so that an image is formed which can be detected by second optics, comprising:first, second and third partial optics and an optical axis as common optical axis for the first partial optics and second partial optics by which the second optics are formed; light coming from the third partial optics and incident in said second partial optics enclosing an angle relative to the common optical axis at which the third partial optics lie outside of an area traversed by the light reflected by the reflecting surface from said second partial optics to said first partial optics, wherein an optical axis of the third partial optics encloses an angle of less than or equal to 90Â° with the optical axis of the second partial optics, and wherein there is provided a device for deflecting the light bundle, especially a mirror or a prism, by which the light proceeding from the third partial optics is directed into the second partial optics, and wherein a pupil surface of the second optics is provided between the first and second partial optics and the device for the deflection is at a distance from this pupil surface which is not more than half of the pupil diameter.
