High Precision Diffraction Slits
OS-8453
Included Parts
1. Single-slit wheel with holder

Introduction
Model OS-8453 includes two slit wheels with holders designed
for use on a Basic Optics bench with a laser and other Basic
Optics components. Each wheel contains several slits and other
patterns. The wheels can be rotated to change the slit pattern illu-
minated by the laser.
Set-up
1. Snap one of the wheels onto an optics bench with a laser and
screen as illustrated.
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.
Beam Widening
When using a green laser (which has a narrow beam) with the
“comparisons” patterns, place a lens between the laser and the
slits. This will spread the beam, making it easier to illuminate
both sets of slits simultaneously.
Sensor-based Set-up
To make sensor-based measurements, use a Linear Translator
(OS-8535), Aperture Bracket (OS-8534A), Rotary Motion sen-
sor, and High Sensitivity Light Sensor. For set-up instructions,
see the manual included with the Linear Translator.

An optics bench can also be purchased separately (part OS-8541 or
OS-8508). A PASCO dynamics track with Optics Carriages (OS-8472) can
be used instead of an optics bench.
