This spectroscope helps teachers to demonstrate spectroscopy simply and clearly.
Fraunhoffer lines. Flame test in chemical analysis. Absorption spectra through liquids. Bright line spectra from discharge tube. Features & specification:
IMPORTANT: Do not use to observe the Sun directly. Doing so can be very dangerous. You can however observe blue sky though the spectroscope and will see Fraunhofer lines.
I can highly recommend this little device. It may look like a toy but it is actually a very well designed and powerful tool with quite good resolution. A nice thing to try is burning salt (sodium chloride) in a hot flame (light over a gas stove) and seeing the bright sodium lines. You can just barely see the sodium doublet if you have good eyes. As mentioned in the description, if you point at the blue sky or even some bright clouds, you can very clearly see all the major Fraunhofer lines. One thing that is difficult is recording what you see with a camera. It's possible but a bit of a frustrating experience because it never looks as good as you can see visually.
