摘要：
The invention relates to a video endoscopic device (10) comprising a camera head (28) and two parallel optical arrangements (16, 24, 26), each made of optical components (16, 17, 24, 26, 27), which are arranged coaxially with one another along a common first optical axis of the optical components (16, 17, 24, 26, 27) of a respective optical ar¬rangement (16, 24, 26) and in the interior of an endoscope shaft (14). The optical compo¬nents (16, 17, 24, 26, 27) transmit an optical image (38) from a distal end (20) of the respective optical arrangement (16, 24, 26) to a proximal end (18) of the respective optical arrangement (16, 24, 26). The camera head (28) is arranged adjacent to or adjoin¬ing the proximal ends (18) of the optical arrangements (16, 24, 26). The camera head (28) contains at least one image sensor (34) comprising a recording plane (32) and at least two projection objectives (30) of which each one has a second optical axis and is arranged and configured to project an image (38) onto the image sensor (34). The optical arrangements (16, 24, 26) each comprise a collimating optical unit (16), arranged at the respective proximal end (18) thereof, for generating an at least approximately parallel beam path (12) at the outlet (18) of the respective optical arrangement (16, 24, 26). The respective collimating optical unit (16) has a third optical axis that is arranged coaxially with the optical components (24, 26, 27) of the optical arrangements (16, 24, 26) or laterally offset by at most half a diameter of the collimating optical unit (16) from the common first optical axis of the optical components (24, 26, 27) of the optical arrange¬ments (16, 24, 26). Each one of the at least two projection objectives (30) is arranged and configured to image the parallel beam path (12), generated by a respective collimating optical unit (16), on at least one focus (36) in the at least one recording plane (32) of the at least one image sensor (34). At least one of the project
