Objective - Scanlab hurrySCAN 10 Installation & Operation Manual

Objective

Caution!
• Before installing the objective, verify its compat-
ibility with the mounted objective holder or
beam exit threads. Otherwise, damage to the
objective and scan head mirrors may result. In
the event of questions, contact SCANLAB.
Before mounting, inspect the objective for scratches,
lens defects and dirt. If necessary, clean as described
in "Routine Maintenance of the Optical Surfaces" on
page 31.

4 Installation
Mount the objective as follows:
Carefully remove (e.g. with a small screw driver)
any protective covers from the objective holder or
the scan head's objective opening.
Remove the protective cover from the objective's
beam entrance side.
Some setups require installation of one or more
seal rings between the objective holder and the
objective. Seal rings should be lightly lubricated
(with vacuum grease). Otherwise, threading of
the objective might be very difficult. Additionally,
some setups require installation of one or more
space rings between the objective holder and the
objective to ensure a safe distance between the
objective and the deflection mirrors. Check for
corresponding accessories in the objective
mounting set.
Caution!
• When installing the objective, ensure that all
components of the corresponding objective
mounting set are used. Failure to install included
seal or space rings can lead to a mirror crash
(resulting from inadequate distance between
the deflection mirrors and the objective).
Furthermore, the beam exit might not be opti-
mally sealed.
Some objectives are secured to their holders via
screws (and washers). However, most objectives
are directly screwed into the objective holder.
Before screwing in the objective, lightly lubricate
its threads (e.g. with vacuum grease) to prevent
cold welding between the objective and its
holder.
