Undergrad Equipment for simple spectrometer

Click For Summary
SUMMARY

The discussion centers on building a simple spectrometer, specifically addressing the use of anti-reflective coated lenses versus standard lenses. Participants emphasize the need for clarity on the desired specifications, including the spectrum and wavelength range, to provide effective guidance. A basic setup is suggested, involving a diffraction grating and a tube, which are commonly found in chemistry kits. The conversation highlights the importance of detailed requirements for successful spectrometer construction.

PREREQUISITES
  • Understanding of basic optics, including lenses and diffraction gratings.
  • Familiarity with spectrometer components and their functions.
  • Knowledge of wavelength ranges relevant to visible light.
  • Experience with sensor technology used in optical devices.
NEXT STEPS
  • Research the specifications and applications of diffraction gratings in spectrometry.
  • Explore the properties and advantages of anti-reflective coatings on optical lenses.
  • Learn about different types of sensors used in spectrometers and their performance metrics.
  • Investigate the design principles for constructing a basic spectrometer setup.
USEFUL FOR

Physics enthusiasts, optical engineers, and hobbyists interested in building and understanding simple spectrometers for educational or experimental purposes.

Spectrometer standard equipment
Hello:

Doing some review work on physics and , trying to build some simple spectrometer, is it possible to use anti reflect coated lenses or should I use normal lenses

Best regards

What spectrum, wavelength range ?
 
Why do you want lenses at all?
Again, you are assuming we can read your mind.

To reduce the size of the light reaching the sensor to enhance the quality
 
Ah...so now there is more than a diffraction grating and a tube. There is some kind of sensor.

We're back where we were "Figure out what I want and then tell me how to build it."

@hagopbul -- If you would like our help in this thread, you need to give us specifications on the spectrometer you want to build, and show us what you have been reading about spectrometers so we can try to offer helpful suggestions. Thank you.

Sadly, I don't think there's been any more thought to it than the Little Rascal's "Hey, let's put on a show!"

The simplest is a diffraction grating in a tube. Zillions have been sold as part of chemistry sets when chemistry sets were a thing. That's clearly not what he wants, as he discusses lenses (which is almost certainly not what he wants based on his description) and sensors. If this is inadequate, he has to tell us where and not rely on our telepathic powers.

Well, I have at least learned something from your reply, even from the question. It never occurred to me I could have a simple spectrometer. For the next comment, can you explain to me what I will use it for? =;-D [No reply needed. How you folks have such relatively kindly replies often feels beyond me, but thanks to your examples I do find it within me to try.]
