Scanner carriage lamp reflector and method of using same |
摘要 |
A screen-printed reflector reflectively redirects light from a scanner bulb in a substantially uniform illumination pattern across a desired scan area of a document to be scanned. A middle or central portion of the reflector is printed with a non-reflective pattern, while the end portions of the reflector are composed of highly reflective polyester textured matte that in combination with the non-reflective pattern substantially equalizes the illumination across the desired scan area of the document being scanned. The manner of using and constructing the screen printed reflector, provides a fast and efficient method for tuning a light distribution profile to provide a sufficient light reflective pattern that compensates for non-uniform light distribution patterns produced by scanner bulbs.
