Wireless Diffraction Scanner • OS-8441

The Wireless Diffraction Scanner combines a position sensor with a light sensor for scanning diffraction patterns. Compatible with PASCO optics benches (or dynamics track adapter carriages), the Wireless Diffraction Scanner is the perfect update to existing PASCO-based optics systems that use the snap-in optics components. An included aperture setting allows for the adjustment of width-measurement resolution (and light attenuation). A hand crank allows for smooth scanning of diffraction patterns. Because of the wireless design, smooth scans are achieved effortlessly!

This unit enables students to scan many diffraction and interference patterns during one lab period. They can study the differences caused by changing the slit width, slit separation, and number of slits. And, by comparing patterns created by a Red Diode Laser to those of a Green Diode Laser, they can study the difference caused by a change in wavelength.

Measurement control is achieved using either PASCO Capstone or SPARKvue software (required). Connect to software using either USB or Bluetooth Low Energy.

The all-in-one design of the Wireless Diffraction Scanner makes setup simple and fast! Quickly adjust light level with the included aperture dial to achieve perfect diffraction pattern scans.

How It Works

The wireless Diffraction Scanner combines an optical position encoder with a light sensor in a carriage system that can be moved using a scanner adjustment wheel. When a diffracted laser beam is aligned with the aperture opening, the resulting pattern can be scanned by turning the adjustment wheel and measuring the light intensity at every position with the internal light sensor. The aperture dial on the carriage can be used to attenuate the light incident on the light sensor. This adjusts the width of the aperture slit (0.1 mm - 1.5 mm). This also determines the spatial width that the light sensor can resolve.
