Green Diode Laser - OS-8458
Designed to be used with Basic Optics System allowing students to explore interference patterns.
Product Summary
This unique diode laser takes the frustration out of aligning the laser beam with the diffraction slits. The horizontal and vertical positions of the beam can be easily adjusted by turning the thumb screws on the back of the laser.
Use the Green Diode Laser with PASCO’s Red Diode Laser to demonstrate the effect of changing wavelength on the diffraction and interference patterns. For example, pass a red laser beam through a double slit. Then replace with the Green Diode Laser by simply pulling the Red Laser off the optics track and clipping the Green Laser into its place. The recorded patterns from red and green lasers show clearly that the longer wavelength (red) is spread out more than the green.
