How to build a spectrometer from the College of Natural Sciences - CSU Online 

Man, I’ve read some of the comments on your video and you’re getting hammered for minor spelling errors and adding music. The fact that you made the effort to demonstrate not only the basics of spectroscopy and proceed to give an example of how a simple device can bring clarity of understanding about colour and light to students is fantastic as far as I’m concerned. My take away from your video is that simple spectroscopes can be made from anything as long as the tubing or box is light-tight (black) on the inside, the diffraction slit is as thin as possible, and the receiver (web cam) in this case is positioned at an angle to the path of the incoming light. With that information and a little bit of self-experimentation, I’m sure people could actually develop their own colorimeters and so on. I’m seriously considering using this approach to spectroscopy as one part of a STEM lesson set for the junior high school students and seniors also who I teach here in Japan. Thank you for the effort and never mind the naysayers. Good job.

may i know the name of the software you use to analyze the spectrum

what program downloadable for windows 8 that goes with?

PLEASE DOES ANYONE KNOW A PROGRAMM I CAN USE AS A SPECTRAL ANALYZER IVE BEEN LOOKING FOR SO LONG

What software did u use???? Plz tell us

How to get absorbance -wavelength curve for a cuvette

Realy nice, but which programm you use for? For me as a German guy, your speach is a littel to fast. I have to watch it more than one times.

Thank you. How can I get a program that is used for computer analysis?

Cool, I've been wanting to make a Michelson Interferometer or maybe even a simple Dispersive diffraction grating spectrometer system using a hard drive actuator. Probably with just a webcam with the hot lens off for a wider range spectra. Was thinking can be more accurate for scanning.

I would like to build this myself, I have a few questions: does it have to be an empty CD disk? also, why an angle of the camera is important? some videos suggest 30 degrees angle

Why not using a cellphone camera?

I'll try making this! thank you!

you must remove the IR filter from the usb webcam to have an entrance for the IR to spectrometre

Did anyone know what apps that he using is on his laptop?

what is the program you are using in the movie ?

Shows video about light ***proceeds to have no lighting

I am willing to make such a instrument too. Can you please tell me what is the software you are using for analysis and how are you feeding the video to the software simultaneously?

How to select wavelength for this caase? for example 400-700nm for analytical analysis of chemical solution or dye /

what software are you using?

Where you had connected DVD Diffraction grading? Have you connected the mirror? At the edge of the slit? Or you have connected in front of the camera-Lens?

Hello, I have a question about where I can find that type of webcam?

Any other diy scientific instruments to make in an afternoon

You could also just tape a piece of DVD over your laptop camera and create a 45 degree rotated blackbox out of cardboard with a narrow slit.

Great help for our lab project! Thank you!

Great job, does it works for UV?

Спектроскоп. Не Спектрометр🙃🐛

.... muy buen vídeo, saludos desde México.....

you used the webcam as a receiver

you can connect the camera directly to the website

Thank you so much! This is great and helpful video.

Cool!!! And simple, good job!

VSH ?

Good video, but lighting could have been better.

Cn anyone tell me how cn i add cuvette here to quantify solution concentration

what is the description of system

Thanks for the video I guess i need that red colour splitter because i am interested to detect metal I heard that near infra red technology is useful to differentiate metal elements

Good project

can we measure absorbance of solutions at uv range ???

this guy is the real deal!

Hello good afternoon. What is the software you use? Where can I download it?

Who the hell even has vhs containers anymore?

You should wash any of the purple dye left on the piece of DVD with a bit of alcohol or acetone.

Where's the test tube insert. What's the point of this without analyzing chemicals

Oh man! Misspelling in the opening screen! "HOW TO BUILD A LOW-COST SPECTOMETER". Way to build credibility!

Aside from too much camera movement and too much animated acting on the speaker's part, this is a great video. You could have raised the volume of his speech a little bit as well.

What's with the f-ing music? Dumb, dumb, dumb. Loud, too.

I use this to burn engine oil from my air plane.. got to make sure that I’m safe or I’ll die.
