012–06348A Slit Accessory
1
Introduction
Equipment
Single Slit Set Multiple Slit Set
4 single slits (slit widths 0.02, 0.04, 0.08, 0.16 mm)
1 variable slit (slit width varies from 0.02 to 0.20 mm)
1 square pattern
1 hexagonal pattern
1 random opaque dot pattern (dot diameter = 0.06 mm)
1 random hole pattern (hole diameter = 0.06 mm)
1 opaque line of width 0.08 mm
1 slit/line comparison, line and slit have similar width
(0.04 mm)
2 circular apertures (diameters 0.2 mm and 0.4 mm)
4 double slits (slit width/separation in mm: 0.04/0.25,
0.04/0.50, 0.08/0.25, 0.08/0.50)
1 variable double slit (slit separation varies from 0.125
to 0.75 mm with constant slit width of 0.04 mm)
4 comparisons: single/double slit with same slit width
(0.04 mm)
double/double slit with same slit width (0.04 mm),
variable separation (0.25 mm 0.50mm)
double/double slit with different slit widths (0.04, 0.08
mm), same separation (0.25 mm)
double/triple slit with same slit width (0.04 mm), same
separation (0.125 mm)
set of 4 multiple slits (2, 3, 4, 5 slits) with same slit width
(0.04 mm), same separation (0.125 mm)
The PASCO OS-8529 Slit Accessory is designed for use with the
OS-8528 Diode Laser on the optics bench of the Introductory or
Advanced Optics Systems (OS-8500 or OS-9254A). The set of two
disks has many different types of slits for diffraction and interference
experiments. The special comparison patterns have two different slits
spaced close enough together so they can both be illuminated by a single
laser beam at the same time, allowing students to compare the two
different patterns side-by-side.

photographic process used to
produce the slit film, the line and slit
may not be exactly the same width.
