• Resumen

  • Color-matching by path-length variation is simple in principle. However, the design of an instrument that makes such matching convenient is another matter. Viewing two light paths through a single eyepiece requires the exercise of optical expertise. It is not surprising that the Duboscq colorimeter was invented by a member of a firm noted for its optical instruments.
