Photos of Spectra

For those doing astro and lab spectroscopy work, I have posted several
spectrum pictures taken with my hand-held spectroscope and with my Nikon
CoolPix digital camera.

All spectra are correctly calibrated against each other in terms of nm.

Note the Fraunhoffer absorption lines on the Solar Spectrum. Na, H_{beta},
H_{gamma} and H_{delta} are visible. They are still a little weak, but my
small spectroscope has very small resolution.

Note also that the only "truly" monochromatic source among these, was the
Red Diode Laser, which emits in the vicinity of 660nm.

Enjoy,

PS: The spectrum of the Propane gas burner is actually molecular and these
are bands, not lines. If anyone has an explanation on what the actual
wavelengths are, please feel free to explain. (Since Propane contains
C/O/H(?), and C's and O's ionization energies are relatively high, I would
expect these bands to be H related, but I am not sure).

There were a couple of mismaches in terms of relative calibration and have
been corrected. If you plan to use this page as a ref or save it to disk,

Great spectra. You may find it useful with solar spectrum to reduce colour saturation or even grey scale them to reveal the dark absorption lines more clearly and apply some sharpening. Thanks for plug for my website!
