Roger, Jan-Peter, Danny, Steve, Matthew, Jose, Fons and Graeme,
I can't thank you enough for all your answers and help with this question. Your answers have helped me and given me the information I needed to find.
Are any of you aware of an inexpensive spectrophotometer capable of measuring the spectral power distribution of light sources in similar increments (5 or 10 nm intervals or segments) ? I have contacted Minolta and they do have some interesting measuring instruments but the cost is a bit prohibitive for my project. In addition it would be nice if the instrument could also measure color temperature and CRI.
I do have another question but will initiate another thread with a different subject line so that it becomes easier to follow.
Thank you very much again for your answers and all your help.
Joseph.
