A kinematic mount, showing some of the mechanism. The most common type of mirror mount is the kinematic mount. [3] This type of mount is designed according to the principles of kinematic determinacy. Typically, the movable frame that holds the mirror pivots on a ball bearing which is set into a hole in the fixed frame. Ideally, this hole should ...
A K-mirror is a system of 3 plane mirrors mounted on a common motor axis which runs parallel to the chief ray of the system. If looking at the system parallel to the mirror surfaces, where only the edges of the mirrors remain visible, the middle mirror and the front and back mirror look like the backbone and legs of a capital-K; this illustrates the origin of the name.
Kinematic determinacy can be loosely used to classify an arrangement of structural members as a structure (stable) instead of a mechanism (unstable). The principles of kinematic determinacy are used to design precision devices such as mirror mounts for optics, and precision linear motion bearings.
The radiators are connected to NIRSpec using thermally conductive heat straps. The mirror mounts and the optical bench base plate all manufactured out of silicon carbide ceramic SiC100. The instrument size is approximately 1900 mm × 1400 mm × 700 mm and weighs 196 kg (432 lb) including 100 kg of silicon carbide. The operation of the ...
An optical mount is a device used to join a normal camera and another optical instrument, such as a microscope or telescope.The optical mount is generally attached to the camera as a lens would on one end, and fastened to the other instrument in a similar fashion.
Kinematics is a subfield of physics and mathematics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies ...
Each link in a chain is connected by a joint to one or more other links. Thus, a kinematic chain can be modeled as a graph in which the links are paths and the joints are vertices, which is called a linkage graph. The deployable mirror linkage is constructed from a series of rhombus or scissor linkages. An extended scissor lift
Illustration of a simple three-axis gimbal set; the center ring can be vertically fixed. A gimbal is a pivoted support that permits rotation of an object about an axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first ...
