Spectrum Charts
Solar Spectrum Chart
This handsome wall chart, covering the
visible portion of the solar spectrum, shows
the wavelength and letter assignment of
the more prominent Fraunhofer lines. These
dark lines, some narrow, some wide, are absorption lines of specific elements in
the Earth’s or the sun’s atmosphere. Chart includes a table identifying the element
responsible for each line in the spectrum and a brief history and description of
Fraunhofer lines. Chart is heavy paper stock with metal binding strips across the top
and bottom. The top strip includes two tabs for wall hanging. Measures 71 x 28 cm.

Spectrum Analysis Chart
This full-color chart is an excellent reference when teaching
spectrum analysis. The bright line (emission) spectra
of ten elements are shown along with the electromagnetic
spectrum with a detailed visible spectrum, the solar spectrum,
Doppler Effect and others. Line drawings illustrate the
methods of producing various spectra and the applications
of spectrum analysis. Measures 69 x 119 cm.

APPARATUS SPECTRUM CHARTS
Spectrum Tubes and Accessories
Spectrum Tubes
Spectrum tubes are glass tubes filled with a gas, usually that of an element or small
molecule. Sealed metal electrodes are located at the ends of each tube. When a
spectrum tube is placed in a spectrum tube power supply and the power supply is
turned on, an electrical discharge is passed through the tube, causing electrons in
the gas to be excited. As the electrons relax, they emit light—a characteristic color
for each gas. When students view the lighted tube through a spectroscope, they can
observe the unique set of spectral lines for each gas. Spectrum tubes should only be
used intermittently and are not intended as a continuous source of light.

Spectrum Tube Power Supply
Student/teacher safety was a prime consideration in the design
of this spectrum tube power supply. Specially molded spectrum
tube sockets easily enable the tube(s) to be placed in position
but also provide maximum protection for the user against
accidental electrical contact. The sockets are fully shielded. A
current-limiting transformer operates from your 110 V AC line to
provide the voltage to operate spectrum tubes. The bottom socket
of the power supply is spring loaded to facilitate easy tube placement
and removal. The power supply is confined within a heavy
metal box. A pilot light, 6-foot grounded power cord and an on/off
switch are built into the unit. Dimensions: 141/2" H x 4 1/2" W x 3" D.

Slides of spectra can be made using the Flinn C-Spectra® and your 35 mm camera.
Film with a rating equal to 300 or more would be required. The Flinn C-Spectra
can be found on page 250.
Focus the Flinn C-Spectra by eye. Set the camera at infinity for 4–5 second
exposure with a wide open shutter. The camera should be on some steady
device like a tripod. Much like the photographer of old, you must rig a light-tight
system (using heavy black cloth) that excludes all light from the camera except
that from the focused Flinn C-Spectra. Since the Flinn C-Spectra is available in
8" x 10" sheets, you can do some lightproof rigging between the camera and the
spectrum tube.
