COMPACT ROS IMAGING SYSTEM |
摘要 |
The pre-polygon scanning path length of a raster output scanning system is reduced by replacing a required cylinder lens, or lenses, with two cylindrical mirrors. One mirror with a negative, concave surface and a second positive cylindrical mirror. The first mirror directs the light beam to the second mirror. The second mirror directs the light onto the facets of a rotating polygon to form a focused beam in the vertical axis of the polygon. The function of the two cylindrical mirrors is to act as a telephoto lens to properly focus the image of the laser at the polygon facet while reducing the total pre-polygon path length.
