DEVICE FOR FORMATION OF LASER RADIATION Russian patent published in 2018 - IPC G02B19/00 G02B27/09 

FIELD: instrument engineering.

SUBSTANCE: laser radiation forming device comprises: structural element (1) with input (2) and output (3) surfaces, first lens group (4) on input surface (2) comprising a plurality of lenses (5a, 5b, ...) located next to each other in the first direction (X) and second lens group (6) on output surface (3), comprising a plurality of lenses (7a, 7b, ...) arranged side by side in the second direction (Y) perpendicular to direction (X). With the help of the first lens, the deflection of the radiation relative to the first (X) and second (Y) directions from lenses (5a, 5b, ...) occurs by an angle different from the angle to which the deflection occurs with the aid of the second lens from lenses (5a, 5b, ...). With the help of the first lens, the deflection of the radiation relative to the first (X) and second (Y) directions from lenses (7a, 7b, ...) occurs by an angle different from the angle to which the deflection occurs with the aid of the second lens from lenses (7a, 7b, ...). Radiation passing through the lens of the first lens group (4) passes exactly through one lens of the second lens group (6).

EFFECT: technical result is to provide a higher brightness and/or improve the design efficiency.
