FIELD: optics.
SUBSTANCE: invention relates to optical instrument making and relates to an optical assembly. Optical assembly comprises a first lens unit and a second lens unit. First lens unit is arranged for imaging an image from the plane of the first image into a magnified real intermediate image in the plane of the intermediate image. Set of possible paths of the beam through the first lens unit determines the first input region in the plane of the first image and determines the first output region in the plane of the intermediate image. Second lens unit is arranged for imaging an image from the plane of the intermediate image into a magnified real image in the plane of the second image. Set of possible paths of the beam through the second lens unit determines an input region in the plane of the intermediate image and determines a second output region in the plane of the second image. Second input area contains the first part of the first output area and excludes the second part of the first output area.
EFFECT: high image quality.
