Can I use an illuminator alone to affect the spectral contrast of my image?

Illuminators have a certain color temperature, which only slightly affects the spectral contrast of an image. When an illuminator is used with color filters, different spectral contrasts can be obtained. Color camera settings (Red/Blue gain level and AWC) in conjunction with lamp selection (quartz-halogen, metal halide and fluorescent) can yield further optimization. Edmund Optics® carries a variety of color filters for our illuminators and light guides.
