Young’s Experiment Set with Laser Pointer


[Product Description]

Young’s Experiment Set (Laser Pointer Type)

[Overall Advantages to Users]

  • Suitable for the experiments of light interference and diffraction using a laser pointer as the light source.
  • High flexibility and portability because the set is a combination of 1) Slide holders & Laser pointer base (D20-1524-X0), 2) Light Diffraction Grating Slide (D20-1842-W1) and 3) Laser pointer (D20-1162; Wavelength = 655nm, Red, or any other laser pointer can be substituted), and optical bench is no longer needed.


  • Light interference and diffraction
  • Young’s experiment

[To all users]

  • Young’s experiment with single and double slit became simple and easily.
  • Optic axis from laser light source can be correctly aligned with the (dedicated) Slide Holder.

[To teachers]

  • Possible to demonstrate anywhere without optical bench and screen.

[To students]

  • Easy to operate because students just need to set slit into the slide-holder and put a laser pointer on the base, after which they only need to adjust the position of beam axis and the slit while emitting the beam and sliding the slide on the holder.
