Spectrum of the sun

An example of the potentiality of the device

Measuring objects at great distances increases the potentiality of the instrument. For example, it is possible to obtain the spectrum of the sun using a set-up slightly different from the one presented before.

Schematic layout of the experiment

Result: Spectrum of the sun

Looking at the spectrum of the sun in the near infrared region is possible to observe the presence of chemical substance in the atmosphere like H2O or O2, which produce absorptions in specific regions of the spectrum.
