Description

Kinematic repositioning with repeatability of several arcsec
Exclusive mounting disk for extra freedom in positioning (850-0020 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.
Unhook the platform from the bottom plate and stow it away with all the units still mounted. Later replace the platform, just as it was, with a repeatability of several arcsec.
The bases use a kinematic scheme, where three steel balls register with a cone, a v-groove, and a flat. The balls and registers are of hardened polished steel.
Hooks prevent a platform from accidental movements.
A bottom plate is fastened through clearance holes or a slot. 850-0020 has a revolving mounting disk – a degree of freedom of positioning.
