Abstract
The monocular device consists of a two-piece (2, 3) longitudinal body with an eyepiece (1) fixed on one of its extremities. The other extremity of the body accommodates internally two biconvex lenses (4, 4') of equal power arranged in the grooves (5, 5'). The distance A between the first (4) and the second (4') lenses and the distance (B) between the second lens (4') and the eyepiece (1) are in a relation A=1/4B approximately.
