High Precision Diffraction Slits
OS-8454
Included Parts
1. Single-slit wheel with holder
2. Double-slit wheel with holder
Additional Parts Required
• Introductory Optics Diode Laser, OS-8528A
• Introductory Optics System, part of OS-8500
Introduction
Model OS-8454 includes two slit wheels with holders designed
for use on an Introductory Optics bench with a laser and other
Introductory Optics components. Each wheel contains several
slits and other patterns. The wheels can be rotated to change the
slit pattern illuminated by the laser.
Set-up
1. Place one of the wheels onto an optics bench with a laser as
illustrated. Place a screen further along the track.
2. Aim the laser at the slit
pattern in the “9 o’clock”
position.
3. Turn the wheel to select
the slit pattern to be illu-
minated by the laser.
4. Observe the diffraction
pattern on the screen.
