摘要

1. Observation device comprising an image converter tube (3) and an optical system (5) which gives a plane and enlarged intermediate image (14) of the exit image of the tube (3), characterized in that it includes a deflecting element (9) of transparent material bounded on one side by a spherical or plane face (91) and on the other side by a reticulated face (92) situated substantially in the plane of the said intermediate image (14) and formed by a plurality of plane microfacets (921, 922) inclined in relation to the optical axis (12) in such a manner as to form between them a plurality of refractive microprisms and a biocular viewing device (10), behind which the observer places his eyes and which is disposed in such a manner that its object focal plane is situated substantially in the plane of the said intermediate image (14) and of the said reticulated face (92).
