Abstract:
A color sensing apparatus includes an optical system that produces a spatially uniform light beam independent of the use of a diffusion chamber, and a color sensor that senses reflected light of a reflection of the spatially uniform light beam, wherein the optical system includes a light integrator with a tapered inlet surface and a lens secured to an exit plane thereof.
