"Activités de comprehension"

Study optics with this complete kit while learning about light, refraction, reflection, convex and concave lenses, and focal length.

Premium line of glass lenses designed specifically for Universities.

Perform many different lessons around reflection, refraction, diffraction, and interference.

An advanced laser ray box that clearly demonstrates the optical axis.

This set has been designed for simple and clear demonstration of the principles of geometrical optics - transmission, reflection and refraction.

High precision, quantitative atomic spectra experiment.

Complete optical bench kit for exploring image formation and lens behavior in physics labs.

Build a periscope to learn about light reflection and line of sight.

Frosted acrylic lenses for optical experiments.

Lessons in Optics and Light in the Palm of Your Hand Colorfully illustrate additive and subtractive color mixing, color transmission, absorption and filtering of the different wavelengths of light with this set of primary and secondary color mixing paddles. You can also use the diffraction gratings in this set to view spectra from different light sources. Show students how a spectroscope, colored lights, and even polarized sunglasses work with the contents of this set.

High quality and low cost make this ideally suited for junior high or high school students.

Set of color filters to be used with ray box

This laser ray box is adjustable, magnetic, and bright enough to use in ambient light.

Project a straight line for mirrors and lenses.

Easily demonstrate the separation of light.

This updated Ray Box uses five super bright LEDs for bright, white rays that are clearly visible.
