MicroLab™ Positioning Stagessocal.mavin.com/pictures/ss/melles_griot.pdfmotion and position of a solid body in space. These six degrees of freedom are the basis of describing the

motion and position of a solid body in space. These six degrees offreedom are the basis of describing the alignment of an opticalcomponent and are the foundation of the kinematic principle—the number of points of contact for a body to be constrained fullyshould be such that each degree of freedom be constrained, butonly once. Using the common Cartesian frame of reference, thedegrees of freedom are specified by the three Cartesian axes; x (theoptical axis), y, and z; together with the angular rotations about theseaxes; vx (roll), vy (pitch), and vz (yaw).

The stages described in this chapter all mate together with acommon hole pattern. All have been designed to be as compact aspossible and to have heights conforming to the 2.5-mm incremen-tal height guideline. The stages can be used individually or combinedto provide positioning and alignment of component holders withfrom one to six degrees of translation or rotation.

$ Single-axis and x-y translation stages

$ Goniometers

Optical components are frequently mounted in optical com-ponent holders, many of which incorporate some means to align thecomponent. For instance, polarizer holders incorporate means forrotation about the optical axis (roll), and mirror mounts usuallyincorporate angular adjustment about axes transverse to the opti-cal axis (pitch and yaw). To achieve many optical configurations,it is convenient to use specially designed stages so that any desiredlinear or angular motion can be applied to the optical component.

Three linear (translational) motions and three angular (rota-tional) motions must be obtainable in order to describe fully the

Single-Axis Translation Stages$ Micrometer or fine-threaded thumbscrew drive

$ 6 mm of travel

$ Stackable for x-y or x-y-z configurations

These compact translation stages provide 6 mm of linear posi-tional adjustment of a 25#25-mm mounting platform. Two drivetypes are available: the 07 TMC 501 and 07 TMS 501 are drivenby a stainless steel, 0.35-mm-pitch (73-TPI) thumbscrew with 1.5-mmresolution; the 07 TMC 502 and 07 TMS 502 are driven by a pre-cision micrometer with a 10-mm graduated scale and 1.5-mm reso-lution. Both have locking thumbscrews. The stages are made ofblack-anodized aluminum.

These stages can be combined to provide x and y motions. The07 ACE 501 angle bracket, described on pages 24.43-24.44,27.23-27.24, can be used to combine three single-axis translationstages to provide x, y, and z motions.

Integral x-y-z Translation Stage$ Fine-threaded thumbscrew drives

$ Precision helix-threaded vertical motion

$ 6 mm of travel in x and y; 3.5 mm of travel in z

This very compact translation stage provides 6 mm of adjust-ment in two orthogonal axes parallel to a 25#25-mm mounting plat-form and 3.5 mm of vertical travel perpendicular to the platform.Adjustment in the x and y axes is obtained with stainless steel,0.35-mm-pitch (73-TPI) thumbscrews with 1.5-mm resolution. Ver-tical motion is accomplished by turning the knurled lower sectionof the stage. The precision helix threads provide smooth verticalmotion.These x-y-z stages are made of black-anodized aluminum.

This stage can be used to position optics held in componentholders. It can also be combined with a low-profile tilt stage, oneof the rotation stages, or a goniometer to provide four, five, or sixdegrees of freedom.

Miniature Rotation Stages $ Micrometer or fine-threaded thumbscrew drive

$ 360 degrees of manual rotation

$ 15 degrees of precision adjustable rotation

These rotation stages combine a full 360-degree range, with18-arc-second resolution in a single compact unit. When the lock-ing thumbscrew is engaged, 15 degrees of precision adjustment areavailable, driven by a stainless steel, 0.35-mm-pitch (73-TPI) thumb-screw for the 07 TRT 507 and by a micrometer for the 07 TRT 508.A 360-degree scale, equipped with a vernier, can be read to 1 degree.The resolution is 18 arc seconds.

The stages are made of black-anodized aluminum. Componentholders or other stages can be attached to the rotation platform,and the rotation stages can be attached to other stages or bases.Using the other stages described in this chapter, multiaxis posi-tioning systems, with both linear and rotational adjustment, can beassembled.

Miniature Goniometers $ Precision rotation at a fixed height above the platform

$ Stackable for two-axis rotation about a common point

Goniometers allow partial rotation (tilt) of a mounted opticalcomponent about an axis at a fixed height above the top surface.These two goniometers have been designed to stack as a pair. Theirdifferent rotational radii are exactly matched to produce motionabout a point at which the two rotational axes intersect. Eachgoniometer is 20-mm high. The model 07 GON 507 stage has arotational axis 12.5 mm above its top surface; the 07 GON 508stage has a rotational axis 32.5 mm above its top surface.

Both stages are driven by a geared knob and have locking thumb-screws. An angular vernier scale on the side of the goniometersprovides an angular resolution of 0.2 degree over a 830-degreerange for the 07 GON 507 or 0.1 degree over a 815-degree rangefor the 07 GON 508. The goniometers are made of black-anodizedaluminum and brass.

Low-Profile Tilt Stage$ Fine-threaded thumbscrew drives

$ Both drives conveniently located on one side

$ Low-profile design

This very compact stage provides tilt about two orthogonal axesparallel to a 25#25-mm mounting platform. Adjustment is providedby two stainless steel, 0.35-mm-pitch (73-TPI) thumbscrews con-veniently located on one side of the stage. The tilt-adjustment rangeis 82.5 degrees in each axis. The stage, which is 10-mm high, ismade of black-anodized aluminum. This stage can be used as alow-profile tilt stage or as a narrow-profile mirror mount. When usedas a tilt stage, its base is attached to other stages or bases withone M2 screw and one M4 screw. When the stage is used as a narrow-profile mirror mount, the three M2-threaded holes alongone edge are used for mounting.
