Introduction
The PASCO OS-8527A Laser Sight Accessory is de-
signed specifically to be used with PASCO projectile
launchers and is an effective accompaniment to Shoot-the-
Target experiments.
Equipment
– Laser Sight Accessory
– 9VDC adapter
Additional equipment recommended:
– PASCO ME-6800 (short range) or ME-6801
(long range) Projectile Launcher
– PASCO ME-6805 Shoot-the-Target Acces-
sory
➤WARNING: Always wear safety goggles
when you are in a room where the Projectile
Launcher is being used.
The base of the Projectile Launcher must be

LASER SIGHT
ACCESSORY
➤CAUTION: This is a relatively safe, low power
laser. Nevertheless, we strongly recommend the fol-
lowingprecautions:
•Never look directly into the laser beam, either di-
rectly, or as it is reflected from a mirror.
•Set up experiments so the laser beam is NOT at eye
level (for spectators who may be either sitting or
standing).
Assembly
➀Set up Projectile Launcher as required.
➁Attach Laser Sight Accessory to rear of Projectile
Launcher with supplied thumbscrew and square nut.
See Figure 1. Face of laser diode unit must be flush
against rear of launcher barrel.
➤NOTE: A greater range of inclination angle for
the launcher can be achieved by attaching the Laser
Sight Accessory to the lower channel of the Projec-
tile Launcher. This, in effect, rotates the Laser Sight
Accessory and changes the direction of the horizon-
tal and vertical adjustments as labeled in back of the
laser diode unit.
➂Plug the 9VDC adapter phone plug into the back of
the laser and turn on the laser.

Laser Alignment
It is necessary to align the laser beam so it passes pre-
cisely through the center of both bore-sights inside the
launcher barrel. See Figure 2.
Projectile Launcher must not be loaded during this proce-
dure.
➀Cutout the supplied laser target fixture (see Figure 5)
and place at the exit end of the Projectile Launcher.
Orientation is not critical.
➁Use the horizontal and vertical adjustment screws to
adjust the direction of the laser beam from left-to-right
and up-and down until the beam is in properly aligned.
See Figure 3.
➂Proper alignment is achieved when a single beam is
observed at the center of the face of the laser target
fixture. See Figure 4.

➤CAUTION: Proper laser beam alignment can
adequately be determined by viewing the laser tar-
get fixture from the front of the launcher barrel, at a
reasonable angle, away from the path of the laser
beam.
➃Remove the laser target fixture and continue with your
experiments.
