Abstract: The invention relates to an objective lens arrangement (101) comprising a front aperture (140), an objective (120) and a liquid lens (110), wherein the objective (120) and the liquid lens (110) are fixedly arranged along an optical axis (OA, OA?) at positions located on an image side (BS) relative to the front aperture (140) and are set up for imaging an imaging beam path presented on an opposite object side (OS) in front of the front aperture (140) in at least one sensor plane (S, S?). The optical effect of the liquid lens (110) can be adjusted in such a way that NED imaging beam paths which can be sharply perceived by a human observer can be sharply imaged in the at least one sensor plane (S, S?) by adjusting the liquid lens (110). The front aperture (140) is designed as an aperture diaphragm for a system entrance pupil (EP) of the objective lens arrangement (101) and has an aperture opening of between one millimetre and six millimetres.
