Make Magazine presents a video demonstrating how to make a 3x3x3 cube made of LED lights. Presenter Bre Pettis explains how to program the LED lights to perform an animation. For further instructions, visit
SPIE Educational Resources

These educational resources are provide by the Society of Photographic Instrumentation Engineers and are intended to introduce the fields of optics and photonics into the classroom. Information is provided on ETOP - Education and Training in Optics and Photonics, Education Outreach Grants, Hands-On Optics, SPIE Scholarship in Optics and Photonics, and more.
Liquid Crystal Sensor

This is a classroom activity to explain liquid crystal sensors for middle school students. A list of activity materials and .pdf handouts are included. The objectives of the activity are to "understand how liquid crystals (LCs) relate to other phases of matter (liquid, solid, gas); observe that liquid crystals reflect many different colors (wavelengths) of light; learn that thermally sensitive LCs...
Double Exposure Makes Dense High-Resolution Diffractive Optics

This article from SPIE discusses an electron-beam-lithography technique which fabricates diffractive optical structures such as classic Fresnel-zone-plate lenses with fine features. "Diffractive optical elements are especially useful in parts of the electromagnetic spectrum, such as the soft x-ray region, where suitable materials for reflective and refractive structures are not available."
Making Math and Science Skills Pay Off

New Technologies Rely on Age-Old Skills

The ATETV project delivers web-based videos to connect students to careers in advanced technology. In this episode of ATETV, lasers and photonics technology, wind energy technology and the importance of mathematics are discussed. Technology being taught at community colleges, such as laser and photonics technologies, is in high demand in industry. Technological education relies heavily on math...

Fiber Optics

Optical fibers transmit light signals and are widely used in the telecommunications industry to transmit data over long distances. Light travels through the core material of an optical fiber by essentially repeatedly bouncing off the cladding material that surrounds the core. Understanding refraction and how light behaves at the boundary of two different materials is the basis for understanding...
Index of Refraction

Refraction is an important behavior of light that can be used to explain the operation of lenses, prisms, and optical fiber, as well as natural phenomena such as rainbows and mirages. The index of refraction, or refractive index, is defined as the ratio of the speed of light in a vacuum to the speed of light in a material. The index of refraction is an important property of optical materials and...
