The Diffraction Slits are an accessory for the Wireless Diffraction System.
See the Buying Guide for this item's required, recommended, and additional accessories.
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.
