To prevent contamination of the air inside the duct from oil or water, a recommended pneumatics kit is
available from Renishaw. This offers double filtration through a 5 µm filter and 0.3 µm mist separator.
Both of these items automatically drain to prevent the system from becoming blocked. However, if the
user chooses to supply an alternative feed, then it is essential that the air feed is well filtered, clean
and dry, and meets the following specification:
Basic filtration
Mist separation
Output pressure
Output flow rate
Particle filtration and mist separation units must be autodraining to prevent moisture being sprayed
into the beam path.
LS06 laser steerer
The LS06 laser steerer is an alignment aid for the Renishaw HS20 laser scale. The steerer allows
easy adjustment to both vertical and horizontal planes reducing the need for final adjustment at the
laser head.
The laser steerer is mounted onto the side of the interferometer nearest to the HS20 laser head using
the clamp screws provided (see figure 15). When installing ensure that the two adjustment levers on
the laser steerer are accessible and approximately in mid-position. This will guarantee full adjustment
range. Total steering range is ±0.6 mrad (0.6 mm/m).
