For optically slowing or completely stopping any object in motion, and for measuring the frequency of periodic motion. Consists of a black metal disk of 250mm diameter with 12 evenly spread radial slits extending to its edge. An axis hole for mounting a handle and a finger hole. Handle and mounting screws are included.

For verifying the laws of reflection and other experiments in optics.

Set of 6 lenses with outer diameter of 38mm. This lens set includes samples of double convex, double concave, plano concave, plano convex and aoncave convex lenses.

Hollow prism is used to study, observe or compare the refraction of light in different liquids of different refractive indices.

Prisms have several uses in optical systems. For example they can deviate a ray, disperse white light into the visible spectrum or erect an inverted image. Great for experiments in dispersion and refraction of light. Face dimension is 25mm. Made of Glass.
Compatible to 3329

The Right Angle Prism unleashes a rainbow of colors from pure white light.  It is precision crafted of clear acrylic and it is available on a blister card.  The length is 1.75 inches.

This lens set is comprised of the most important types of lenses. Optically true with ground glass edges. Includes one of each: double convex, plano-convex, double concave, plano-concave, concavo-convex and convexo-concave, arranged in a velvet lined case. Diameter 50 mm

Solar Cells also called photovoltaic cells are finding their way into thousands of uses world wide.  This kit is an economical introduction to photovoltaics, also known as PV.

This is a pen shape magnifier/ microscope with a magnification range of 16X up to 32X.

Discover the power of the sun with more than 10 experiments.  You can produce some serious energy with this kit.  A solar energy lab complete with converging mirror, wooden stand, clear plastic test tube and glass thermometer.  Instructions are available online.

Wooden and polished. Mounted on base with slot to hold lenses or mirrors. Can be used with meter scale to form simple optical bench.

FIVE-COLOR Sets are ideal for optical transmission measurements, solar monitoring, attenuation of laser beams, and demonstration of laser light's monochromatic character.

For Demonstrating important principles of optics such as reflection by various shapes of mirrors, refraction through several types of lenses, total internal reflection and dispersion. The apparatus consists of a metallic disk about 30cm in diameter, graduated around the circumference in 360 degrees. A handle on the back can be used to rotate the disk in a vertical plane about a horizontal axis perpendicular to the plane and passing through the center of the disk.

This hand held Magnifier Glass can be used for examining biological and geological specimens in the field and laboratory.
