This semi-quantitative spectroscope is a simple and economical alternative to expensive equipment.

This safe spectrum power supply features encased spectrum tubes.

Every classroom that wants to investigate spectroscopy needs a good-quality spectrum tube and power supply.

Explore The Absorption of Light

The exciting demonstrations connect students to core physics and physical science concepts.

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.

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.

The replacement chemicals kit contains 5g each of calcium chloride, cupric chloride, cupric nitrate, lithium chloride, potassium chloride, potassium nitrate, sodium bicarbonate, sodium chloride, strontium chloride and strontium nitrate.

Rectangular blocks in a variety of sizes and are designed for use as an index of refraction plate.

A classical experiment to determine the speed of light in air.

Great optical bench accessory.
