This Diffraction Grating Demonstration Slide has three 20mm x 10mm gratings with 100, 300, and 600 lines per mm, mounted between glass plates. The viewing area of each section is 15mm x 10mm. Three lenses on one slide can be used to demonstrate diffraction of light or to measure wavelengths of light. 

A WHOLE NEW VIEW OF DIFFRACTION!

Finally, the fundamental concepts of Diffraction can be clearly observed and demonstrated for your students!  Attempting to show the factors which affect Diffraction; finding the correct slit sizes, manipulating different colors of LASERs, switching between gratings, even changing distances between the slit and the screen, has been traditionally difficult to set up in the classroom…  until now.  With JC LAB’s new triple Diffraction Grating, demonstrating diffraction of light concepts has never been so easy and definitive.  There are three 20mm x 10mm gratings with 100, 300, and 600 lines per mm, mounted between glass plates.  Used in conjunction with a mounted red/green dual LASER , the students will be able to vary wavelength, slit size, pattern distance, even display multiple diffraction patterns overlays for any classroom activity, including precise quantitative measurements for your favorite diffraction lab.
