Demonstrating the capabilities of my spectrometer

A project log for DAV 4 UV/VIS Spectrometer

Well, this is the next evolutionary step from when I first bought the Plab 2.5 spectrometer kit

  1. Further demonstrating the capabilities of my homemade spectrometer is a calibration curve done on 2 stroke motor oil:
CFL spectra (compact fluorescent light)

Graph showing cfl plot blue band at 436nm and green band at 547nm

correction curve showing calibration quality fit of 3, target is always a fit of "0" but alas, soooo...far away!

After upgrading the DVD grating this weekend I naturally had to run a series of tests to recheck alignment and resolution, so this is a great demonstration of what a homemade spectrometer can do!
