Patent ID: 7643210

Claim:
Night vision binoculars, comprising: an angled input lens ( 1 , 4 ); a light intensifier tube ( 2 ), wherein the input lens is combined with the tube to form a first scene image from a light flow from the scene in a viewing axis (AX), an optical separator ( 8 ), positioned at the output of the tube ( 2 ) which separates the first image at the output of the tube ( 2 ) into two optical channels (BYZC, BCW), which is to say a first optical channel (BYZC) and a second optical channel (BCW), wherein the binoculars are characterised in that they comprise; a plane of reflection ( 8 ′) common to the first optical channel (BYZC) and the second optical channel (BCW); a first optical combination comprising two first convergent groups (V 1 , V 2 ) positioned on either side of a first reflective angled surface ( 5 ), to form, from the first image, a first intermediate image on the first optical channel (BYZC), a second reflective angled surface ( 6 ) transferring the first intermediate image to the common plane of reflection ( 8 ′), so that the first intermediate image is sent to a first eyepiece channel, with an axis (CA″) parallel to the viewing axis (AX), via said common plane of reflection ( 8 ′); a second optical combination comprising two second convergent groups (V 1 ′, V 2 ′) positioned on either side of the common plane of reflection ( 8 ′), to form, from the first image, a second intermediate image on the second optical channel (BCW), wherein the common plane of reflection ( 8 ′) forms an angle on the second optical channel (BCW); and a third reflective angled surface ( 7 ) transferring the second intermediate image to a second eyepiece channel with an axis (WA′) parallel to the viewing axis (AX).
