Instruction Manual for
the PASCO scientific
Model OS-9102C
INCANDESCENT LIGHT SOURCE

Description

The PASCO Scientific Incandescent Light Source, OS-
9102C is intended to be used by students in an educational
environment to perform experiments in basic optics.
The Incandescent Light Source produces a light output of
approximately 15 candle power in the visible spectrum. It
is powered by a very stable, well-regulated power supply
that ensures the light source output will not drift in
intensity. The output is bright enough and stable enough to
perform demanding experiments such as investigations into
Young's coherence.
The Incandescent Light Source mounts magnetically to the
PASCO Introductory and Advanced Optics System's optical
benches. A knob is provided on the top of the unit to adjust
the filament position of the lamp.

Operating Instructions

1. Place the light source on the optical bench with its
steel pads on the bottom touching the magnetic strips
on the bench, and its back edge pressed up against the
alignment rail of the optical bench. To minimize
bending of the optical bench, it is advisable to place
the light source near one end of the bench.
2. Connect the light source to the 12 VDC, 2.5 A power
supply provided. Connect the AC line cord to the
power supply and to an appropriate power source.
3. When necessary, adjust the large knob on top of the
light source to align the bulb filament along the optical
axis of the optical bench. The bulb filament will move
in the same direction that the knob is turned.
4. Mount filters, apertures, variable diaphragms, etc. on
the magnetic surface of the front panel.
