fle.X-plate
Related Products
The fle.X-plate is a monolithic adjustment unit with flexures, ideally suited for centering fibers, fiber-optics and spatial filters like pinholes, down to μm-accuracy and even sub-μm level. It is available in 2 different versions.
-
- 0.5 mm full adjustment range for X and Y direction
- Central mounting bore with Ø12.5 mm. Enlargement to Ø25 mm with adapter G061624000
- Compact monolithic design, no moving parts
- Displacements based on short and special shaped flexures. No play, friction or hysteresis
- X and Y translations are coplanar. No unwanted movements causing tilts
- Fully centrosymmetric design with the "thermal center of gravity" at the mounting bore
- Pure X & Y translations without any parasitic effects like tilts
- Four M2.3 screws for fixing in the LINOS Microbench are included in delivery
- Each translation is controlled by two screws, a pulling screw and a pushing screw
- Final super-fine adjustment is realized by controlling the final torque level of both screws, which action automatically secures the locking of the final setting at the same moment
- Extremely good long-term stability over a wide temperature range due to the monolithic and centrosymmetric design, the "thermal center of gravity" and the locking mechanism
- fle.X-plate XY Steel is made from hardened steel and ideal for permanent setups and production equipment. It offers highest precision, sensitivity and stability better than 1 μm
- fle.X-plate XY Al is made from anodized aluminum. Its sensitivity and stability is at μm level
- Both plates are delivered with tools for the adjustment screws
Main features, common to both versions
fle.X-plate XY Steel and fle.X-plate XY Al
-
- X and Y direction, each have two adjustment screws, one pulling screw and a smaller one pushing via a steel ball.
- Coarse to fine adjustment is done by adjusting both screws simultaneously at a rather low torque level, in order to arrive easily near the intended position within several μm's.
- Subsequently this X or Y position is then gradually blocked by enlarging the torque levels of both screws to a much higher fixation level. By tuning the torque level of one screw or of both screws the position is being blocked for the long term but, simultaneously, can also being tuned down to sub-μm finesse by means of the torque ratio between the two screws.
- Hertz' deformation by tuning the preload on a steel ball, rather than usual displacement from a spindle, is the basis of combining sub-μm tuning with automatic blocking.
- Usually securing of the final position is done subsequently with lock nuts, but this always influences the adjusted position. This problem is avoided by the automatic blocking mechanism of the fle.X plate.
