Claim:
A day-night vision device for observing objects, comprising: a day vision channel including: a first lens unit; and one or more refractive or reflective first optical components; a night vision channel including: a second lens unit; and one or more refractive or reflective second optical components; an image sensor; an additional channel including a graphic display for providing additional information as an additional image; a deflection means; and a receiving channel having an eyepiece unit, wherein the deflection means includes a partly transparent beam splitter and is rotatable about an optical axis of the receiving channel so that, by the deflection means: radiation information from at least one of the day vision channel, the night vision channel, or the additional channel can be fed into the receiving channel; and radiation information from the additional channel can be superposed with radiation information from the night vision channel; or radiation information from the additional channel can be superposed with radiation information from the day vision channel; an optical connection from the day vision channel to the receiving channel being capable of being switched on and off.
