Several manufactures of radiometers make models that measure the 
     wavelengths.  EIT and I.L. are two of them.

With UV exposure units the intensity of the lamps is measured 
with a radiometer. In our imaging departments, we keep a close eye on 
our exposures as far as intensity. However we've been overlooking an 
equally important factor, UV wavelength, and the radiometer doesn't 
measure that.  I am looking for a practical method of measuring and 
monitoring the wavelength of the lamp as it degrades. If anyone can 
steer me in the right direction or has any input on this matter, I 
would appreciate talking with you.
