U400-AC In Stock

The U400-AC by Newport is an ULTIMA Precision Kinematic Optical Mount, designed to accommodate high precision optics with a diameter of 4 inches. Leveraging an array of spring-loaded pawls, this mount ensures a secure and reliable grasp on optics, firmly positioning them against three distinct points on the front plate of the mount. For applications that demand unwavering stability, the pawls of this mount can be fine-tuned to achieve a heightened level of security in the optical setup. One of the standout features of the U400-AC is its ability to significantly mitigate wavefront distortion within the optics. This advantageous effect is achieved through the axial application of forces on the optic, resulting in minimal wavefront distortion.

The U400-AC is fortified with robust rear plates, a substantial front plate, and rigid springs. This strategic reinforcement not only enhances the long-term stability of the system but also confers remarkable protection against undesirable vibrations, fostering an environment conducive to precision optical applications. Versatility remains a hallmark of the mount's design, as it readily accommodates an assortment of actuators. This adaptability extends to motorized actuators, micrometers, and adjustment screws, offering users a broad spectrum of options to suit their specific requirements. Importantly, this mounting solution effectively mitigates mount-induced wavefront distortion often associated with side set screw configurations. Moreover, the U400-AC simplifies installation with its well-considered design, featuring clearance mounting holes on both sides of the mount that can accommodate M4 or 8-32 screws.
