In days of old there was the Klett Colorimeter.  It measured in "Klett units"
rather than OD.  I think because the tubes used were not square so path length
was not fixed.  They were popular in student labs since it was almost 
impossible to destroy them.  Oh, I just saw that you can still buy them!  
Do cost a bit more now.
