Other Equipment
Optics Bench: Beginning and Basic Optics components, such as the color mixer and view screen, snap into the wide central chan-
nel of the optics bench. Place the base of the component on the bench and push down firmly to snap it in place. To move it, squeeze
the tab on the side of the component and slide the component along the bench.
Use the metric scale on the bench to measure the positions of components.
Viewing Screen: Mount the screen on the bench to view the individual and mixed colors of light from the color mixer
Geometric Lens Set: The lens set consists of two double convex lenses, each 50 mm in diameter, with focal lengths of +100 mm
and +200 mm.
Usage
.
Optics Bench with Lens
Mount the Color Mixer at one end of a
PASCO Optics Bench. Connect the
power supply to the back of the Color
Mixer and plug the power supply into
an electrical receptacle.
Mount a Viewing Screen near the
other end of the optics bench. Mount a
+200 mm focal length double convex
lens near the Color Mixer.
Adjust the position of the lens and the
viewing screen as needed in order to
see the overlapping circles of red,
green, and blue color as large as possi-
ble on the view screen.
Use the knobs on the back of the Color
Mixer to adjust the light intensity for
each color. For example, you may
need to turn down the intensity of the
red LED slightly in order to more
clearly see white as the blended color
in the center of the pattern. Turn the knob fully counter-clockwise (right-to-left) to turn off the color and turn the knob fully clock-
wise (left-to-right) to make the color as bright as possible.
CAUTION: The Color Mixer light-emitting diodes (LEDs) produce intense light. Do not look directly into the Color Mixer when
it is turned on.
