MEX18

Motorized laser beam expanders MEX series are used to increase the laser
beam diameter and adjust divergence. Standard or custom-made beam
expanders feature a unique mechanical closed loop sliding-lens design
ensuring high pointing stability and minimal dimensions.
M a i n fe a t u re sHighest beam pointing stability (< 0,1 mrad)
All-in-one design with integrated controller■ Two lens simultaneous movement assuring no misfocus■ Absolute encoder (both lenses)■ Adjustment time <1s (all magnifications)■ Fused silica optical elements■ No homing after switching on/off■ Diffraction limited performance for all magnifications
