WTB: USB spectrometer

[Sta]

Hello folks!
Many of you know that my 589nm DL Spartan has been acting strangely - it's been putting out at least 5 different lines depending on temperature.
In order to solve this mystery I need a spectrometer, preferably one that is calibrated and able to be connected by USB. I will consider any offers; however, it would be best if the asking price is <$300. Thanks in advance!

Since you don't currently have a spectrometer why don't you try making one? StyroPyro did a video on this. Been following your posts. Looking forward to seeing the results

I'd love to do that, but it's not precise enough, nor can it be done in a short span of time. Remember, my 589 changes wavelength very readily and without warning.

This is the right price, but you'd have to calibrate it yourself

Those are ok. They're not amazing. Anything that's within a good accuracy that he wants will likely be at least 500+ minimum. Spectrum analyzers are usually several thousand dollars new. And they hold their value. Plus then you need fiber and programs. Realistically if he wants to spectrometer something as a one time deal it would be easier to send his laser to someone who has one that is reputable. 7 bucks lol
