General Information
The Newport Accessory Shelf provides a convenient under-the-table plat-
form for mounting and storage of controllers, lasers, and other instruments
when working with any of the Newport Vibration Control System.
The Newport AS-1568 Accessory Shelf is often used in conjunction with a
AH Series Access Hole to direct the output from a laser, mounted on the
Shelf, to the equipment mounted on the table.
The Shelf is a 2 inch thick rigid honeycomb panel with welded steel panels
on all six sides.
Please read this instruction manual thoroughly before assembling the
Newport AS-1568 Accessory Shelf.
The components of the Newport AS-1568 Accessory Shelf are packed in a
single box. Be sure the number of boxes you received is equal to the total
number listed on the label (for example, if a box is labeled 1 of 4, there
should be 4 boxes).
Use the diagram in Figure 1.1 to locate and identify each component as
you remove it from the box. Carefully inspect all components for shipping
damage. Report any shipping damage immediately to Newport and the
shipping company.
The following terms are used in this manual that relate to your safety.
Warning is used to indicate dangers that could result in personal injury.
Caution is used to indicate situations that may result in damage to
components of the Newport Vibration Control System.

Assembly
The Newport AS-1568 Accessory Shelf is fastened to the underside of the
Newport Vibration Control System. Before proceeding with the installation,
be sure that the table top is stable and securely fastened to the support
isolators.
Use the following procedure to assemble your Newport AS-1568 Accessory
Shelf.
A. Remove the shelf from the packing carton and place it on the floor
below the table.
B. Refer to Figure 2.1 for correct placement, and mount the four shelf
posts to the underside of the table using the 1⁄4-20 ×3⁄4" bolts. Screw
the bolts in approximately four turns so that the shelf posts hang
loosely below the table.

Section 3
Operation
The Newport AS-1568 Accessory Shelf provides a convenient support and
storage shelf for measurement equipment and lasers that should be
mounted below the optical table.
Newport AS-1568 Accessory Shelves require little maintenance. No peri-
odic maintenance is required.
3.2.1 Cleaning
The Newport AS-1568 Accessory Shelf is made of painted steel. It may be
cleaned by applying non-abrasive liquid household cleaner to a rag and wiping
the surface dry. Avoid abrasive cleaners as they may scratch the painted
surfaces.

Section 4
Troubleshooting
4.1.1 System Shelf Bends From Load
The shelf has a maximum load capacity of 100 lbs (45 Kgs). If your load
exceeds this value the shelf may bend enough to cause laser beam misalign-
ment. Distributing the load over the entire surface of the shelf will reduce
bending.
4.1.2 Table Isolation Performance is Degraded
Table isolation performance may be degraded if electrical or coolant lines
are connected to equipment on the shelf. Vibration conducted to the shelf
from ground by cables or hoses can be minimized by providing generous
service loops. Reducing coolant flow rates can reduce coolant generated
vibration.
Cooling fans or other moving components in equipment mounted on the
shelf may cause vibration of the table surface.
4.1.3 Beam Alignment is Difficult to Maintain
Avoid installing large heat sources on the shelf. Temperature differences
between the top and bottom table skins can cause the table to bow.
