®

The optical bench and its accessories are used in ex­periments with optical components for research and
demonstrations where the highest degree of precision
is required for adjustment of axes and distance mea­surement. The swivel joint permits experiment con­figurations where the beam path is deflected.

The optical bench made of triangular-profile, black
anodised aluminium is tilt-proof, deformation- and
torsion-proof as well as anti-slip. A continuous scale in
cm/mm division is attached to both sides. Two grooves
on the supporting surface are available for optional
mounting on two rail supports or one support and a
single-point support. There are three drill holes at the
front end for fastening the end plate or the swivel joint.

U10302 0.5 m Weight: approx. 1.75 kg

1.2 Set of supports for the optical bench

This set consists of two rail supports and a single-point
support made of black anodised aluminium. It allows
for height adjustment of the optical bench in a four­point or three-point support configuration.

Length of the supports: 270 mm

1.3 Swivel joint

The swivel joint consists of black anodised aluminium
and can be swivelled around an angle of 90° in both
directions. A protractor has been included to set the
angle. In the rotational axis there is a sleeve to mount
optical components.

2. Operation

2.1 Assembly of the rail supports

• Insert the square-socket screws into the guide
groove under the profile rail and fasten by tight­ening them.

• Adjust the height using the adjustment screw.

• Use the grub-screw to secure the settings.

2.2 Assembly of the swivel joint

• Take off the front plate by loosening the three fas­tening screws.

• Place the swivel joint on the rail and secure it by
tightening the three screws.

• Connect the swivel joint to the second rail in like
fashion.

2.3 Recommended rider and assembly aids

• For the assembly of elements in the optical axis:
Optical rider (U10310 to U10312 and U10315 to
U10317)
Double rider (U10340 to U10342)

• To tilt element out of the optical axis:
Tilting rider (U10330)

• To slide elements perpendicular to the optical
bench axis: sliding rider (U10320)

• To position elements adjacent to the optical axis:
Extension arm (U10331)
