CONTRAst enhancement diagonal 1                           Ced 1

Picture
What is a Contrast Enhancement Diagonal and Why do you need one? 


A Contrast Enhancement Diagonal or CED is fresh idea at the approach of reducing secondary color inherent in ED and Achromatic refractors.  All recent attempts have been by using filters to block specific wavelengths of light (usually violet).  A filter creates another problem by going through additional glass.  Since the development of the dielectric diagonal, we thought it would be easier to customize the reflected image by allowing excess violet, deep red, and even yellow-green to pass through.  The result is a very natural and balanced image not achieved by using a filter.  No extra optical element is necessary.
