Picomotor Piezo Center Mount, 4.0 in. Diameter, 2-Axis

The 8824-AC provides the precision and stability of the Picomotor actuator utilizing the ULTIMA Kinematic Optical Mount. It provides smooth, reliable motorized adjustment along with carbide pads, thick front and rear plates and optimized, stiff springs to improve the long-term stability and provide greater protection against vibrations. Spring-loaded pawls gently, but securely, hold a high precision 4 inch (101.6 mm) diameter optic from the back against three points on the front plate of the mount. Wavefront distortion in the optic is minimized because the forces acting on the optic are axial, instead of radial and are more distributed. For applications requiring secure mounting, the pawls can be tightened further, compressing the springs, and clamping the optic between the three points on the front plate and the pawls. Convenient clearance mounting holes on each of two sides are compatible with either 8-32 or M4 screws providing quicker, more precise, and more secure mounting.
