Definitions
- This invention relates to a substantially kinematic mounting for a rigid object and finds particular application in the mounting of optical elements in an interferometer. 5
- Traditional methods of holding rigid objects firmly in place can make the maintenance of the objects difficult.
- the optical elements In • interferometers the optical elements must be held firmly but without distortion and the usual methods of gluing or bolting the element in place makes re-aligning and replacing those elements 10 troublesome.
- a substantially kinematic mount for a rigid object comprising planar, linear and point contact constraining means is provided.
- At least one of the constraining means comprises a rigid body and a resilient body which together are adapted to 15 urge said rigid object into contact with the other two of the constraining means.
- the rigid body and the resilient body may together synthesize either a point force, a linear force or a planar force on the object.
- the resilient body may be made of polytetrafluorethene
- PTFE polytyrene resin
- another suitably elastic material may be substantially tubular, cylindrical or spherical in shape.
- the resilient body may be a spring or spring like device.
- Figure 1 shows a substantially kinematic mounting for a block
- Figure 2 shows an Michelson interferometer employing the mounting.
- a block (1) is constrained between a rigid pin (2), the faces (3 and 4) of rigid blocks (5 and 6) and a tubular spring- ' like member (7) made of PTFE.
- the pin and the rigid blocks are
- FIG. 2 a beamsplitter block (1) and a compensator plate block (11) of a michelson interferometer, substantially as described in patent application GB90-19647, are mounted using a substantially kinematic mounting as shown in figure 1.
- Two rigid blocks (5 and 6) and two rigid pins (2 and 12) are mounted on a support surface (8).
- a tubular spring-like member (7) and a rigid face (3) of the rigid block (5) cooperate to create a force which urges the beamsplitter (1) into contact with the pin (2) and the planar face (4) of rigid block (6).
- the tubular spring-like member (17) and the rigid face (13) of the rigid block (5) cooperate to create a force which urges the compensator plate (11) into contact with pin (12) and the planar face (14) of rigid block (6).
