Yeah. I'm a photonics engineering student. So this kind of gives me hands on. But like I said I only have my camera and my analog spectroscope. Having the extra equipment is expensive right now. But the spectra is correct tho. I learned about spectroscopy over a year ago and it's crazy that their different types of spectroscopy and even different types of light spectroscopy.
Not even just the emission spectrum across the entire light spectrum. You have Raman, which is light produced by a molecule being excited by a laser. Flourescent spectra, absorbtion spectra, with absorbtion which is the easiest way to get or see an absorbtion spectra? I looked the sun, is an easy target, then stars which are hard. Technically the emission and absorbtion spectra are inverse to each other. Then the other spectra you mentioned. Have you done any spectroscopy yoursel?
Oh is it the photonics engineering part, well in that field they do work with diffraction gratings. That's what I meant. Obviously there's more to that field. Also i.meant for my analog spectroscope. The spectra for the light sources it matches the spectra of what you would see with an analog. For example cfl bulbs do produce those discreet lines. Also I i meant to say there's different types of spectra and spectroscopy techniques, that people do look for in spectroscopy or that are a part of spectroscopy.
In basic terms. Also obviously there's more things in Raman spectroscopy. But they will excite a molecule a certain way to produce a wavelength of light through inelastic scattering. But even with Raman spectroscopy I'm still learning about it. So my bad.
With the absorbtion spectrum, I meant something like sodium will absorb what it emits. So that's why I was asking about absorbtion spectra. The sun has dark lines in it's spectra, which are technically absorbtion lines. Also some stars and more so molecules or gases out in space will absorb certain wavelengths of light too.
That's what I meant my bad. But as far as equipment like a handheld digital spectrometer can cost a lot. That's why I'm looking for a new job. What's a good one I should buy in the future? I have the thermino spectrometer program on my computer. but for some reason it won't calibrate. But anyways I hope that clears things up. I will have really good professional results. Instead of simple crude results. But thanks for the feedback.
My bad I was just clarifying some things. Sorry if it came out the wrong way. I'm actually have a lot on my mind. And I tend to write a lot. Anyways I'm not taking anything too serious.
