Diffraction Slits

Product Code: OS-8442

Description

The Diffraction Slits include a selectable wheel with 16 interference patterns designed to match the height of the PASCO Diode Lasers. The slits are constructed using vacuum-deposited chromium on glass and clip directly to a PASCO Optics Bench. The slit selector wheel eliminates the frustration of trying to change the slits in a darkened room. To change the slit being illuminated by the laser, the slit wheel is simply rotated to the next positive click to lock another slit into position.


Features

  • Vacuum deposited chromium on glass
  • Single Slit (four variations)
  • Double Slit (four variations)
  • Multiple Slit (2, 3, 4, 5)
