Equipment for simple spectrometer

Click For Summary

Discussion Overview

The discussion revolves around the construction of a simple spectrometer, focusing on the use of lenses, specifically whether anti-reflective coated lenses or normal lenses should be utilized. Participants explore various aspects of spectrometer design, including the spectrum and wavelength range of interest, as well as the role of diffraction gratings and sensors.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the specific spectrum and wavelength range the OP intends to measure.
  • Another participant questions the necessity of using lenses in the spectrometer design.
  • The OP clarifies that lenses are intended to reduce the size of the light reaching the sensor to enhance quality.
  • There is a suggestion that the simplest design involves a diffraction grating in a tube, which has been commonly sold in chemistry sets.
  • Some participants express frustration over the lack of detailed specifications from the OP, indicating that more information is needed to provide helpful suggestions.
  • One participant reflects on their learning from the discussion and expresses curiosity about the potential uses of a simple spectrometer.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the optimal design or components for the spectrometer, with multiple competing views and questions remaining unresolved.

Contextual Notes

There are limitations in the discussion due to the OP's vague specifications and assumptions about what participants might infer regarding their needs. The discussion also reflects a dependency on the OP providing more detailed information for effective assistance.

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.

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."

Thread is reopened provisionally, but unfortunately the OP is on a short vacation from PF.

@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.]
