Using the Rotary Motion Sensor
Mount the Accessory Holder on the Optics Bench
The Accessory Holder snaps into the Optics Bench. To move the
Accessory Holder along the bench, grasp the base of the holder
and squeeze the locking clip inward. Continue to squeeze inward
on the locking clip as you move the holder to a new position.
When you release the locking clip, the Accessory Holder is held
firmly in place.
Rotate the
Polarizer
Rotate the Polarizer
by grasping the edge
of the Polarizer. As
you turn the Polar-
izer, the plastic belt
will turn the three-
step pulley on the
Rotary Motion
Sensor by the same amount. When the Rotary Motion Sensor
is connected to ScienceWorkshop or PASPORT interface, you
can measure the angular position of the Polarizer to within
one-quarter degree.

Aperature Bracket
The Aperture Bracket has two main components: the Light
Sensor Mount and the Aperture Bracket Holder.
Light Sensor Mount
The Light Sensor Mount has an Aperture Bracket Screen, an
Aperture Disk, a large thumbscrew, and a threaded post. You
can use either the large thumbscrew or the threaded post to
attach a Light Sensor to the Light Sensor Mount in one of two
positions. Use the threaded post if you want to hold the Light
Sensor Mount in a rod clamp. The large thumbscrew or the
post is stored in the threaded storage hole on the Light Sensor
Mount when not in use.

Aperture Bracket Holder
Two metal thumbscrews attach the Aperture Bracket Holder to
the back of the Light Sensor Mount. The Aperture Bracket Holder snaps into place anywhere along the
center section of the Optics Bench that is part of the OS-8515 Basic Optics System. To move the holder
along the bench, grasp the base of the holder and squeeze the locking clip inward. Continue to squeeze
inward on the locking clip as you move the holder to the new position. When you release the locking clip,
the holder is held firmly in place.
