@zander I'm going to use dvd-R disc for that.

@zander yeah, it's right. But we know the sensor alignments and spectral wavelength for different colors.

@zander I'm going to use 1000lines/mm transmission grating instead of a prism. Also I'm looking for make a reflective grating from using a blank dvd p...

@zander it's for color identification like purposes as a start. As a further development I will find and work with absorption and reflective wavelengt...

@davee thank youuu!, it's clear and valuable information. My target is making a spectrometer using a ilx554b ccd sensor for low cost and precise. Cali...

@davee yeah, it's right!. Thank you sir!

@zander thank you for your information and help💪🧡

@davee thank you sir. Is this code okay with ccd read and analog read? This is micropython code I made. The range in that code is used for tes...

@davee thank you sir, I appreciate your response. I'm going to make a spectrometer using that sensor and pico. I know it's not easy. I used to convert...

@zander yeah, it's CCD (charged coupled device)sensor. I'm looking for make a spectrometer using it with pico.
