leading to a wide pupil.) If the exit pupil were larger, not all exiting light could be utilized by the eye; one would lose image brightness. (That could happen in atelescope, for example, when using an ocular lens with too low magnification, i.e., with a too long focal length, or...

A telescope eyepiece (1) is described which has an exit pupil at a great distance for imaging an image plane (9) or a reticle to infinity and comprises a field stop (3), arranged on the light entry side (2), and two lens groups, separated by air in the light direction, as a ...
FIELD: physics.;SUBSTANCE: telescope has an exit pupil position which does not change when magnification is changed outside the eyepiece and an entrance pupil which is superposed with a first lens during high magnification. The telescope has a positive objective lens which includes a first positive...
Regarding a sighting telescope comprising an objective and a reversing system, a first and second image planes respectively being configured between the objective and the reversing system and on a reversing system's side facing away from the objective, where an intermediate image projected by the ...
Design of off-axial Gregory telescope design with freeform mirror corrector In this paper a well-known approach is used for calculation of off-axis three-mirror telescope. It includes usage of conic cross-sections properties, each of the sections forming a stigmatic image. To create a compact ...
It is a telescope eyepiece (1) comprising an far projecting exit pupil for imaging an image plane (9) or of a reticle according to an infinite, and consisting of a light entry side (2) arranged field stop (3) and two in the light direction by means of air separate lens groups as ...
