Diffraction Slit Sets
The PASCO Model OS-9165 includes four slides:
Set 1: Four single slits.
Set 2: Four double slits.
Set 3: Four multiple slits.
Set 4: Aperture and diffraction patterns.
The PASCO Model OS-9179 includes two slides:
Set 1: Four single slits.
Set 2: Four double slits.
Electroformed Slits
Specifications:
Material: .005 mm electroformed nickel
Tolerances: +/- .005 mm
Slit Width and Spacing:
The label on the top of each slide lists four patterns: A,
B, C, and D. The slits are arranged in that order from
left to right on the slide. Figure 1 illustrates the relation-
ship between the label and the slit specifications.
Note: The 'SLIT SPACE' dimension is from center
to center of each slit
Example for Double Slit Slide:
Pattern 'A' (furthest on the left) consists of two slits,
each .04 mm wide and spaced .250 mm apart, center to
center.
Pattern 'B' (second from the left) consists of two slits,
each .04 mm wide and spaced .500 mm apart, center to
center.
In Pattern 'C' and 'D' the width of each slit is .08 mm, while
the center to center spacing is the same as for 'A' and 'B'.
