Optics Bench without 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 Color Mixer. Adjust the position
of the viewing screen so that the overlapping circles of red, green,
and blue color are as large as possible on the screen.
Use the knobs on the back of the Color Mixer to adjust the light
intensity for each color. 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) pro-
duce intense light. Do not look directly into the Color Mixer when
it is turned on.
Standalone
Connect the power supply to the back of the Color Mixer and plug the power supply into an electrical receptacle.
Point the Color Mixer at a piece of white paper or another white surface so that the front of the Color Mixer is parallel to the white
surface. Use the knobs on the back of the Color Mixer to adjust the light intensity for each color.Turn the knob fully counter-clock-
wise (right-to-left) to turn off the color and turn the knob fully clockwise (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.
Color Mixing
The three primary-color lights produce three “secondary-color”
lights when mixed. The blue and red lights blend to form magenta,
the blue and green lights blend to form cyan, and the red and green
lights blend to form yellow. All three colors blend to form white.
You may need to adjust the intensity of the individual colors in order
to produce the white light.
Note that the blending of primary-color lights and the blending of
primary-color pigments (such as paints) produce different results.
Other
The ventilation slots in the color mixer housing help the LEDs oper-
ate at a low temperature, and this extends their useful life. Typically,
a light-emitting diode of the type in the color mixer has a life span of
50,000 hours. However, because of the efficiency of the circuitry in
the color mixer, the LEDs may last much longer.
