FIELD: physics, optics.SUBSTANCE: invention relates to optics. The weight-compensated mobile suspension of a focusing lens (12) of a laser system (10) comprises: a force generator for generating a force (G) which balances the weight of the focusing lens (12), a transmission mechanism which enables to apply a counteracting force (G) to the focusing lens (12) and enables compensating movement of the focusing lens upwards/downwards. The suspension also includes a device which guides movement of the focusing lens such that during compensating movement of the focusing lens (12) upwards/downwards, its optical axis (O) maintains at least its orientation and, preferably, its position in space.EFFECT: during movement, the optical axis of the lens maintains at least its orientation and, preferably, its position in space.9 cl, 1 dwg |
