Equipment Note: The Pasco
Introductory Optics System
Figure 1 shows all the equipment in the OS-8500 Introductory Optics System. The system also includes a fitted box with
cutouts for each component. Please replace all components in their places after each lab period before returning the box.

Holder
The optics bench is shown here. The light source, component holders and ray table base all attach
magnetically to the bench as shown. For proper optical alignment, the edge of each of these
components should be mounted flush to the alignment rail which is the raised edge that runs along one
side of the bench.
Ray Table Base
Note: Avoid scratching or otherwise abusing the surface of the magnetic pads. If they get dirty ask for
them to be cleaned by the technician.''
Incandescent Light Source
The light source is shown in Figure 3. To turn it on, connect the power cord to any grounded 105-125
Vac receptacle, and flip the switch on the rear panel to ON. If at any time the light fails to come on,
check with your instructor.
The filament knob on the top of the unit moves the light bulb from side to side. The notch at the bottom
indicates the position of the light bulb filament, so that accurate measurements can be made during
experiments.
Component Holders
The optics set comes with three regular component holders (Fig. 4) and one holder designed for use
with the ray table. The regular component holders attach magnetically to the optics bench as in Figure 5.
The ray table holder sits on the edge of the circular ray table. The notch at the top of each holder is for
centring components on the holder. The notches in the base of the regular holders are for accurate
distance measurements on the bench scale.

Figure 7: Ray Table Component Holder, The Ray Table Component Holder is designed to sit on the circular ray table. It has little hooks on the bottom and if
you put it on the bench it wobbles. So if your component holder wobbles, it's the wrong one.
