Two-sided
viewer designed by an astronomy teacher for ease
in seeing and identifying element and molecular
spectra from gas tubes.
User Comments
"Easier to use than hand spectroscopes!"
"Comparisons are speedy."
"Viewing spectra...no eye straining."
Features
- No longer hunt the Internet or multiple
textbooks for reference spectra--the 16 most
common gas tubes found in phsyics, astronomy and
chemistry labs/classes are on the Viewer!
Spectra, divided into four groups from the
Periodic Table, that are included are: Noble
Gases--Helium, Neon, Argon, Krypton, Xenon;
Metals--Sodium and Mercury; Non-Metals: Hydrogen,
Nitrogen, Oxygen, Chlorine, and Iodine; Molecules
and Mixtures--Air, Water, Carbon Dioxide.
- Extra-large viewing window, 3 inches (7.5 cm),
makes it easier for one or more students to see
the spectrum.
- The comparison spectra were made using the same
diffraction grating film, sharing the same scale,
resolution and light distribution as the viewed
spectrum when directions (included on both sides
of the Viewer) are followed.
- Measuring scales are approximately proportioned
to sine-theta instead of linear like most hand
spectroscopes, accommodating for the Law of
Diffraction and removing common systematic errors.
- Brightest visible line markers help eliminate
false identifications.
- Specifications: 5.75 x 8.5 inches (~14.5 x
21.5 cm). Comes with instructions/notes
sheet.
Costs:
1-$9.50, Prepackaged
sets: 10 - $85, 30 - $228, 40 - $285.
FREE SHIPPING for orders (USA) over $100 when
prepaid!

Is your campus/school/neighborhood
really "green"? Here's a
two-sided viewer for studying local
area lighting for light and energy
efficiencies, and light
pollution.
Useful for physics, astronomy and
environmental science courses,
teachers or informal educators.

The front side
shows spectra of High Pressure and Low Pressure
Sodium, Metal Halide, Mercury Vapor, Fluorescent
and CFL, and Incandescent lights, plus
specialized lights such as LEDs, Neon and "Black
Light".
The obverse side has notes about the different
lights, a table of representative energy, light
and other characteristic values, instructions on
surveying one's neighborhood, and a general
description about continuous, absorption and
emission spectra!
