3.2.1.2 The Height Adjustable Positioning Table

clamp in a substrate, a substrate support plate or a FINEPLACER

plate to hold the substrate.
• ... will secure the substrate position by its mass and its friction against the
base plate (70), supported by the electromagnet buried in the base plate.
• ... can be moved easily for coarse positioning on an air cushion so that it may
float above the base plate (70), using the micrometer screws (50) and (51) as
temporary handles. Once coarse positioning is achieved, releasing the foot
switch will lock the table in the optical axis.
• ... can be fine aligned using the x and y micrometer screws.
• ... can be rotated around the optical axis to achieve θ correction, prevented
against accidental x or y shifting by the electromagnet.
A fundamental rule is that the height of the placement surface of the substrate must
be equal to that of the pivot arm axis. To achieve this with substrates to be laid onto
heating plates or support plates, the continuously height adjustable tracks of the
positioning table have to be used to maintain the correct working height.
