Three degrees of freedom with common centre of rotation
For precision alignment of prisms, beamsplitters, etc.
Mounts horizontally or vertically


Three Angle Prism/Beamsplitter Table 6TP169 provides non-calibrated tilt motion in three planes. It is ideal work platform for prisms, beam splitters and mirrors, which needed to be precisely adjusted in angle about thre orthogonal axes. Various opto-mechanical mechanisms can be quickly and conformably attached to the top of the table stage using Spring Clamps 4SC. Prisms can be fixed to the top of the Table using Bar Clamp 4BC32 or V-Clamp 4VC41.
Every three Angle Prism/Beamsplitter Table 6TP169 is provided with three drives ensuring rotation about three different axis. Two lower screws turn the top of the table around two orthogonal horizontal axes, upper screw ensures rotation around vertical axe in plane. All three rotations are fully independent and all three axes are fully orthogonal. Fine pitch screw threads ensure high resoliution provide a stable platform. All three rotations are about a point 27 mm below the center of the top plate.
Three Angle/Beamsplitter Table 6TP169 can be attached to STANDA optical table or to another stages with Table Clamp 3TC5. Also four attachment thread M6 holes in the bottom of the table are provided. The main elements of the table are made from black anodized aluminium.

Kinematic repositioning with repeatability of
several arcsec
Exclusive mounting disk for extra freedom in
positioning (6KB131 only)
Hooks of spring steel for reliable locking and
quick release

A kinematic base is used for repeated positioning of groups of units mounted on its platform.A platform has M6 mounting holes. Alternatively, fit an M6 screw through a clearance hole from beneath. You unhook the platform from the bottom plate and show it away with all the units still mounted. Later you replace the platform, just as it was, with a repeatability of several arcsec. The bases use a kinematic shceme, where three steel balls register with a cone, a v-groove, and a flat. The balls and register are of hardened polished steel. Hooks of spring steel prevent a platform move by accident.

You lift the units mounted on the platfrom as a group. The platform is repalced with a repeatability of a micro-radian. The platform has patterns of M4 and M6 mounting holes. Alternatively, fit M6 screws through its clearance slots from beneath.
Two high strength magnets lock the platform to
the bottom plate. The bottom plate is fastened by M6 screws through a pair of transversal clearance slots. Push the special lever to lift the platform with minimal jolts.
