  • A Synthetic quarts crystal that is lab grown.  This crystal will be cut into sections that will be manufactured into optical components and electrical quartz crystal oscillators. Quartz creates an electrical signal with a very precise frequency that is used to provide a stable clock signal to the rest of the circuit.

  • Fragment of an Abalone shell; color enhanced scanning electron micrograph (SEM) of a section through an abalone (Haliotis sp.) shell. The shell is composed of layers of overlapping platelets of calcium carbonate crystals, or aragonite,  Between the layers are thin sheets of protein (not seen). This structure makes the shell much stronger than the materials would be in any other arrangement.  Abalones are edible mollusks found in warm seas. The thin layers of shell reflect light using the wave nature of light.  Each thin layer reflects a particular wavelength – together the layers reflect wavelengths of light that constructively interfere to create bright greens and blues. Magnification: x1000 when printed at 10 cm wide.

  • The quartz crystal optical wedge is a simple technique to aid in specimen identification by inducing a color gradient in a polarizing microscope. The wedge is made from a crystalline block of quartz cut into a wedge angle so that the optical axis of the quartz is oriented either parallel or perpendicular to the edge of the birefringent crystal. A typical quartz wedge is useful for measurements of petrographic specimens (rock and mineral thin sections) or other birefringent materials. The quartz wedge compensator is also employed for the determining the direction of anisotropy (crystalline fast and slow axes orientation) in birefringent specimens.

  • Thin film interference on soap film. Bands of color are created by white light shining on a film of soap. Some of the light reflects off the surface of the film, while the rest of the light travels through the film and reflects off the back of the film.

  • A .22 caliber bullet is fired from a rifle. The pullet is passing through a thin sheet of glass. Here the bullet is seen in a polarizing interferometer. The different colors of light represent different air pressures. The clear bow wave in front of the bullets shows that the bullet is moving faster than the speed of sound. The exact velocity of this supersonic bullet can be calculated from measurements of the bow wake angle. This image freezes the motion by using a high speed flash with a duration of 1/2,000,000th of a second.

  • A Hasselblad 500EL medium format camera is shown in X-ray. This is the model of camera used by the Apollo Astronauts on the surface of the moon. To save weight, only the film pack containing the exposed film was returned to earth. The camera body and lens were left on the surface of the moon.
