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.

Note: Laser on/off switch must be held down to stay on. Consider trying the Adjustable Laser Stand #92-7660, which will hold down the 'on' button for our laser pointers.

Perfect for lighting kitchen counters, our 120V Undercabinet Bar Light with selectable 3 CCT technology and a High-Low switch to provide quality illumination for all tasks.

Products being sold are not toys. They are for Educational / Laboratory use only. They are not for use by children 12 and under.

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.

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. Two AAA batteries included.
