SPECTRA OF FILTERED LIGHT SOURCES


This web page will be for nothing but spectra of filtered light sources:

Ocean Optics USB2000 Spectrometer donated by P.L.
As of 10-10-07, I've been using a PC2000-ISA Spectrometer from Ocean Optics that I received several years ago, but that I didn't have a home for until now.
As of 03-08-08, I once again have the USB2000 spectrometer, enabling color spectra again.



Filtered Light Sources
