Three diffraction gratings (100, 300, 600 lines/mm) enable direct comparison of diffraction patterns for deeper understanding
Protective glass plates encase each grating to preserve optical clarity and durability
Large-scale patterns make it easy for students to observe and analyze light behavior
Supports quantitative labs and precise wavelength measurements for hands-on learning
Simple classroom setup eliminates the need to swap gratings or reconfigure equipment
Diffraction grating slide for optics demonstrations
The Demo Diffraction Grating gives students a whole new view of diffraction, making one of the most fundamental—and traditionally difficult—optics concepts clear and accessible. This demonstration slide features three diffraction gratings with 100, 300, and 600 lines per millimeter, all

Worked great
The grating work well having three different line configuration on one slide

Great demo piece
Just got a lot of raves on this at our regional STEM fair
