An opto-lithographic device comprising a lens system (13) arranged between a mask support (25) and a substrate table (33) and telecentric on one side, the lens system (13) and the mask support (25) being secured to a first holder (21) and a second holder (23), respectively, which can be displaced both simultaneously and relatively be means of a first actuator (183, 187, 189) and a second actuator (197, 199) for adjustment of focusing and enlargement. The invention provides the possibility of a simple correction of focusing and enlargement when this focusing and this enlargement are varied inter alia to pressure or temperature variations. |
