Description
A slide containing four sets of double slits is positioned in the laser beam using a slide holder on a cross-carriage mount. Any of the four sets of slides can easily be slid into the beam. The four sets of slits have slit width a and separation d as follows: ◙◙a=0.04mm, d=0.25mm; a=0.04mm, d=0.50mm; ◙◙a=0.08mm, d=0.25mm; a=0.08mm, d=0.05mm.
