The Dual Red-Green Laser features two lasers, one red and one green, all in one pointer. Great for demonstrating wavelengths, refraction, and diffraction, this handy laser can project red and green beams individually or together. When used with a diffraction grating, students can easily observe the spacing differences between the antinodes in the red wavelengths and green wavelengths right from their seats. Then they can use the spacing separations to measure the wavelengths of the different colors. Metal case and two AAA batteries included.
Please note: This laser is intended for the convenience of having two lasers in one, and the beams are not calibrated to be exactly parallel.
