The PASCO Color Mixer can be used as both a demonstration tool and as an expansion piece to the Basic Optics System.  

The intensity of the red, green and blue LEDs of the Color Mixer can be individually adjusted to easily vary the intensity of any or all of them.  Demonstrating additive color mixing is as simple as using any flat surface to project the light upon.

Show how white light is produced and explore the secondary colors of cyan, magenta and yellow.  Vary the intensities to produce nearly any color.

The Color Mixer also connects easily to an optics track and can be used with components of the Basic Optics system in laboratory investigations.  As shown to the right, using a lens and viewing screen the Color Mixer can be focused and projected at each lab station.  And by adjusting the screen and lens position, students can control the overlap of colors.

The Color Mixer (OS-8496) is an accessory for the:
