Color Separation Filters

Color imaging and measurement systems utilize color separation
filters as well as prisms to differentiate the prime color wavelengths.
Image capture systems divide light into red, green, and blue before
reaching the detector. Image delivery systems recombine the red,
green, and blue to form an image. In either case, system performance
can be enhanced by carefully controlling the wavelengths and the
areas of overlap. Systems which use prisms to control the spectrum
can have enhanced performance using color separation filters.

Color filters have application in color imaging and reproduction
systems such as analog and digital video cameras, digital still
cameras, digital and video projectors, scanners, and copiers.
They also have application in color measurement instruments
such as colorimeters and radiometers.

For applications with demanding specifications Omega Optical
offers High Purity Color Separation Filters and Sets with extremely
high optical purity. These filters eliminate any overlapping wavelengths
between colors.
