Hi Eric,I have investigated them for spectroscopy (I know Lothar Schanne who is mentioned on the Gerd Neumann site) but this is a rather different application where spectral content rather than field uniformity is more critical. Talking to Lothar, from the spectral content point of view I would say that they would be ok for BVR (even too bright for normal imaging flats perhaps) but the output is much lower in the I band.CheersRobin
