The U100-AC2K ULTIMA Aperture Base Precision Kinematic Optical Mount uses spring-loaded pawls to gently, but securely, hold high precision 1 inch (25.4 mm) diameter optics 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. Like all ULTIMA mounts, thick front and rear plates and optimized, stiff springs improve the long-term stability and provide greater protection against vibrations. This mount is provided with two high precision, 100 TPI adjustment screws with knob. The actuators can be quickly changed to accommodate a broad selection of adjustment screws, micrometers, and motorized actuators. ULTIMA® Precision Kinematic Optical Mounts minimize mount-induced wavefront distortion. Side set screw mounting, found in most optical mounts, is fine for many applications but our tests have shown that this technique induces wavefront distortion in the optic if the set screw is tightened a little too much. 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.

U100-AC2K ULTIMA孔径基础精密运动光学支架使用弹簧负载的棘爪轻轻，但安全，保持高精度1英寸(25.4毫米)直径的光学从背面对支架前板上的三个点。由于作用在光纤上的力是轴向的，而不是径向的，而且分布更广，因此光纤中的波前畸变最小。对于需要安全安装的应用，棘爪可以进一步收紧，压缩弹簧，夹紧前板上的三个点和棘爪之间的光学元件。与所有ULTIMA支架一样，前厚板和后厚板经过优化，刚性弹簧提高了长期稳定性，并提供了更好的防震保护。该安装具有两个高精度，100 TPI调整螺丝和旋钮。执行机构可以迅速改变，以适应广泛的选择调整螺丝，千分尺，和电动执行机构。天涯®精密运动光学支架mount-induced波前畸变最小化。在大多数光学安装中发现的侧置螺钉安装在许多应用中都是可行的，但我们的试验表明，如果固定螺钉过于紧固，这种技术会导致光学中的波前畸变。方便的间隙安装孔在双方都是兼容的8-32或M4螺丝提供更快，更精确，更安全的安装。
