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. Provides a way to demonstrate how televisions produce a full range of colors and a visual demonstration to discuss UV absorption and the color of the ocean or why Rayleigh scattering produces an orange sunset.
The Color Mixer also connects easily to an optics track and can be used with components of the Basic Optics system in laboratory investigations. Using a lens and viewing screen from the Basic Optics system 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 Accessory Kit has 18 cards (64 mm x 89 mm) and a manual with 9 associated lab activities. Each of the 7 filter cards has its transmission spectrum printed on the card. Each of the 11 color cards is printed with a different color and its associated relative reflectance spectrum. Printed colors are defined by the Pantone color matching system. This accessory kit was designed especially for use with the Color Mixer.
See how the PASCO Color Mixer and Accessory Kit can be used to investigate additive color mixing, transmission through colored filters, reflection and absorption with color cards, and fluorescence.
