Operation
➀
Place a slit set and the Diode Laser on the magnetic strips of the
optics bench about 7 cm apart. Position the optics bench so the
Diode Laser is about 1.5 m from a vertical, smooth white
projection surface such as a wall, cardboard, etc.
➁
Align the slit set and the Diode Laser on the optics bench by
abutting the edges of the brackets to the side railing of the optics
bench.
➂
Select the desired slit by rotating the disk until it clicks into place
with the slit at approximately the location of the laser beam on
the disk.
➃
Adjust the alignment of the laser beam with the slit by moving
the laser beam up-and-down and back-and-forth with the vertical
and horizontal adjustment screws until the diffraction pattern on
the projection surface is most intense.
➄
Slide the slit set back-and-forth slightly to find the position that
results in the most intense diffraction pattern.
ä Note: After the initial adjustment,
little or no additional adjustment to
the alignment of the laser beam
with the slit will be required when
you change the slit selection.
