RADIOMETER
Radiometer
A fun, vivid way to demonstrate heat transfer! The wings in the radiometer are alternately dark and light. When the light strikes the wings, it transfers heat to each one, but not at the same degree. The light wings reflect the ray and the dark wings absorb the rays. As the light gets brighter it creates more heat and spins the wings faster. (7" x 3-2/5" x 5";.25lb). |

COMPACT OPTICAL BENCH
Compact Optical Bench
This unique optical bench is completely self-contained and extremely compact! The anodized aluminum channel
opens up to form a long two-meter bench, allowing testing of longer than usual focal length lenses. This bench
can also be used as two individual one-meter optical benches. The exclusive design of the lens holders allows
instant changing of lenses and accessories without fussing with clips or screws and the holders slide smoothly
along grooves molded within the case. Everything except the light source folds up quickly into a package slightly
over 1/2 inch thick and can be set up in under one minute! Comes complete with two aluminum benches, six
different 38mm lenses, two optical screens, two object markers, four lens holders, one mini flashlight with clips
and one mini candle which are your light sources. Instructions are provided. (42-1/2" x 4" x 2-1/2; 3.75lbs). |

SPECTROMETER ADVANCED
Advanced Spectrometer
Designed for easy set-up and use. This specrometer's sturdy iron base
incorporates a 20cm-diameter divided table with highly visible etched
graduations and a Vernier scale that can be read to a resolution of 1
minute of arc. The revolving 7cm-diameter prism support rotates 360
degrees and has a height adjustment of 2cm, thereby accommodating
a wide range of test conditions. A built-in illuminated auto collimator
eliminates the difficulty of telescope-collimator alignment. Accessories
include an illuminated magnifier, glass diffraction grating and holder, autocollimation
mirror, power adapter, brush, screwdrivers, extra bulbs, and
instruction manual. |

SPECTROMETER BASIC
Basic Spectrometer
Great for high school laboratories - a perfect device for any intermediate-level
classroom! Built from sturdy metal, this unit includes an adjustable collimator tube,
telescope, and prism stand. It provides a high quality optical system and an easyto-
read etched scale, which allows the student to measure spectrum lines with
a resolution of 50A. Light is directed in the collimator tube and focused to the
adjustable telescope, which has a scale inside to allow special lines to be reliably
measured. Includes a 600-line millimeter diffraction grating, grating holder, 3x2.5cm
equilateral glass prism, prism hood, which helps block stray light from entering the
spectrometer, and instruction manual. |

KUNDT'S APPARATUS
Kundt's Apparatus
Measure the ratio of the velocity of sound in brass
to the velocity of sound in air! A brass rod is rubbed
with a bow, which causes the rod to vibrate. Sound
waves inside the tube cause lycopodium powder to
accumulate at nodal points. By measuring the spacing
between the nodal points and comparing this value
with the length of the brass rod, the ratio between
the speed of sound in brass is obtained. Instructions
provided. (36" x 8" x 5"; 3Ibs). |
