Calibrating the spectrometer

Hello, I'm Hanisa from Indonesia. I got project from my lecturer to build a pinhole camera and find it's resolving power using a home-mad low-cost spectrometer. So I built one. And now I'm here to calibrate the intensity and wavelength. Thank you.

Hi, it looks like your spectrum is quite blurry -- see the examples in the activity here: https://publiclab.org/n/13410

Do you think you need to work on focusing the camera, or could you upload a photo of your setup so we can help you debug?

Is this a question? Click here to post it to the Questions page.
