How to Make DIY Spectrometer | Optical spectrum analyzer | Light analysis

This spectrum analyzer can analyze light, including infrared (IR) and ultraviolet (UV) light. It uses DVD Disk that works like a diffraction grating and splits light into the rainbow, the software then analyzes the rainbow. (A rainbow actually is the light spectrum)
In this video, I also explain why incandescent light bulbs are not energy efficient.

Wow, I must say that this is a really nice tutorial indeed! Cheap and surprisingly efficient :) Just one note though: you could've covered the slit on the wood up with something (say two razor blades) to make it even thinner, because the shortcomings of a wider slit (namely distortion and ghost images) was really apparent from the video as well ;)

Best of the best in the diy field, many thanks!

[neelk]

was looking all day at a way to get an IR spectrum measurement cheaply. Absolutely brilliant!

[iberiuspred]

The incandescent light is a black body radiator so the spectrum of that light should follow Planck's law. If not, then something is wrong with your spectrum analyzer.

very ingenious use of a dvd as a diffraction grating....

[mernokimuvek]

You will get better results if you remove the blue dye from the split DVD. You can also use CD but the resolution is lower. The CD can be used without any modifications as a reflective grating. DVD can also be used as a reflective grating but the blue dye will interfere a bit.

omg you saved like thousands of bucks :) suscribed!

I need buy a webcam for this specifically.
Any suggestions? Preferably one w/out the IR filter if possible lol!

[krishnamarella]

I finally got something useful in youtube I particullarly benefit with this video damn it saved from tomorrow's project seminar thanks brother 😊😊

[thingmaker]

Thank you for this excellent demonstration, it is very inspiring! Would something like this be capable of at-home metallurgical analysis with a proper vacuum?

[MiG-IsGOAT]

Amazing tutorial! can I use this to analize rocks, or other objects?

[MikkoRantalainen]

Could you link to the camera you used? Not all cameras have IR filter that's this easy to remove.

[eduardojmdutra]

That is awesome! Will definetly try this with my students when the pandemic allows!

[AnotherCoyote]

woah this is cool. Okay so NOW how do we make this homemade Spectrometer into a molecular scanner so we can tell if food or water is safe? I wanna know!

[biotechnologistagri]

Thank you for the interesting video however, you have not mentioned that how you synchronised your camera with your software and which software did you use for it?

[rathnamegha]

Hey! Great video but what if I want to introduce a sample and measure the transmittance/absorbance. How do I introduce the sample in the set up? And if I have preset filters how do I obtain data from the set up?

Great instructional video!

However, Infra-red energy is not 'wasted'. We need deep reds, near IR and IR light in the morning to produce elevated levels of mitochondrial ATP (literally our life energy) and also prepare ourselves for exposure to mid-day UV.
Then again in the early evening we need it to repair damage caused by UV and to also switch from serotonin production to melatonin production.

So... LED and fluorescent lights that lack deep red, near IR and IR combined with our indoors life style are detrimental to our physical and mental health.

Incandescent light bulbs are the closest we can get to our ancestral life style of sitting around the campfire before sleep. And in a properly insulated house in the cooler months, their 'wasted energy' means our heating system works 60-100 watts less per light bulb used. So the argument that they are not good for the environment is complete bunk.
Whose environment is it anyway? Because LEDs and fluorescent lights aren't good for OUR environment, and that's before even talking about the Mercury used in CFLs.

Great, amazing

Can you please share some information on the software used in this project?

Those lamps should give sharp emission, instead in your spectra are band. You should reduce the slit size with razors.

The Retina borrows from IR light to see with contrast. You need IR light. Without it, you'll notice things go a bit blurry.
