A system for providing color analysis of a toner image on an image bearing surface with a spectrophotometer is provided. The system includes an illuminator positioned adjacent to the image bearing surface and configured to emit a light beam at the image bearing surface, a linear sensor positioned adjacent to the image bearing surface and configured to receive the light reflecting off the toner image on the image bearing surface, a gradient index lens placed in the optical path of the light beams reflecting off the image bearing surface between the image bearing surface and the linear variable filter; and the linear variable filter positioned between the linear sensor and the gradient index lens. The system is devoid of a collimating lens positioned in between the gradient index lens and the linear variable filter, and the linear variable filter and the linear sensor are spaced apart by a gap. |
