Essential Physics Optics System

Essential Physics Optics System

EP-6478   - 

The included rechargeable Light Source has four colored LEDs on a 2-cm square, making it easy to observe image inversion and magnification. The RGB center LED makes it a breeze to show color mixing. This Optics set comes complete with a 1.4 m precision rail, 50 mm lens mounts, 50 mm concave and convex lenses, mirrors, a refraction cell, diffraction gratings, and more.

Essential Physics Light, Color and Optics Teacher Resources

Essential Physics Light, Color and Optics Teacher Resources

EP-6481   - 

Contains the 12 lessons as student assignments as well as lesson plans, presentations, simulations and more.


Introduce your students to the science and technology of light including reflection, refraction, color, intensity, lenses, mirrors, real and virtual images, human vision, digital imaging, and the quantum theory of light.

  • 12 lessons
  • 5 interactive simulations
  • 8 interactive equations
  • 12 slide presentations
  • 12 lesson plans
  • 12 student assignments

The Ergopedia Optics Kit is a complete laboratory for learning about light, color, and optical technology. Three 50 mm optics mounts slide easily and then lock down with thumbscrews. The light source makes a perfect illuminated “object” for optics experiments, and the fixed spacing of the colored LEDs makes it easy to observe and measure image properties such as magnification, inversion, and brightness.

I am interested in Free access to the Essential Science Modules

Please note: Essential Science Modules are currently in use by students across the country. Therefore, it is crucial that only educators access the teacher's material.

We will send you an email with ONE authorization code: the code will contain both teacher and student editions. This may take up to two business day while we verify your school and district information. We appreciate your understanding.
