The U50-G ULTIMA® Gimbal Optical Mount has a radically simple way of tilting an optic without translating its surface. Conventional gimbal mounts tend to be large and complex to allow high precision true gimbal motion at the optic surface. As a result, they are usually expensive. The ULTIMA-G has a simple patented design, allowing cost-effective, true gimbal mounts without the usual complexity. 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 1/2 inch (12.7 mm) mount is provided with two high precision locking, 80 TPI, hex adjustment screws providing a ±5° range. The actuators can be quickly changed to accommodate a broad selection of adjustment screws, micrometers, and motorized actuators. What makes the ULTIMA-G unique? The optic surface is mounted at the center of a sphere. Rotation of the sphere results in pure tilt at the center, without the translation found in all kinematic optical mounts. That means your beam will go exactly where you expect, without having to make iterative adjustments of the axes. The optic mounts from the rear so that the optical surface is at the plane of rotation, regardless of the optic thickness. Slotted mounting holes on two sides are compatible with either 8-32 or M4 screws for convenient mounting.

万向VS非万向调整架

 

 

万向调整架有着与光学元件的中央前表面相交的旋转轴。 当调节调整架时，只有光束角度发生变化，而光束长度没有变化。 相比之下，非万向调整架会在调整角度时缩短或者延长光束路径。

 

分束孔径

 

 

ULTIMA万向调整架具有一个专门为分光设计的孔径。由于中空半球设计，光束被允许传输通过孔径，实现光束反射和透射。孔径入口还设计了一个深45度倒角，以接受宽角度的光束。
