United Scientific® Laser Diffraction & Interference Demonstration Kit – Includes Red & Green Lasers, Slit Slides, Activity Guide

Explore the principles of wave optics with the United Scientific® Laser Demonstration Kit. Designed for classroom and lab use, this complete laser diffraction and interference kit includes red and green Class 3R laser pointers, a stable mounting base, and multiple diffraction and slit pattern slides. Students and educators can create, observe, and measure precise interference patterns and diffraction effects on any projection surface. The included activity guide supports guided learning and hands-on experimentation in physics and optics.

Two slides feature various double slit configurations for comparing how slit width and separation affect light behavior. Additional slides include single slits of varying widths and a 300 lines/mm diffraction grating for advanced exploration. A handy clip holds the laser on during experiments for continuous use. Perfect for high school, college, and physics lab environments.
