The 8071-M XYθxθy Motorized Four-Axis Tilt Aligner increases the utility of our popular kinematic stages by motorizing each of the axes. The addition of Picomotor™ actuators to each stage allows remote high-resolution (<30 nm) adjustment of various combinations of X, Y, θx, and θy. The Model 8071-M four-axis aligner is ideal for positioning modulators or isolators and for coupling light into waveguide devices. M4 tapped holes. Use with two 8725 multi axis adapters and one 8742 controller/driver or one 8742-4-KIT to control all 4 axes (sold separately).
