摘要： The present invention is directed to a laser printer including a printer controller, a printhead including a plurality of lasers formed in an array for receiving modulating image data from the printer controller, a variable magnifying means such as a zoom lens, and a drum on which a receiver member is mounted on which an image is to be printed. The printer controller is arranged to selectively use any one of a set of predetermined microdot matrixing values and a separate sub-microdot matrix associated therewith, and distribute image data to the plurality of lasers based on such microdot and sub-microdot matrixing values. The variable magnification means (e.g., a zoom lens) applies optical magnification or demagnification to light beams from the array of lasers to provide selective variable microdot matrixing values between the predetermined microdot matrixing values of the set. Therefore, any dot density between a low and a high microdot matrix value of the set of predetermined microdot matrixing values is produced using combinations of microdot and sub-microdot matrixing by the printer controller and variable magnification of the zoom lens.

摘要： An optical scanner is disclosed for scanning a light beam onto a receiving medium. The scanner includes a rotatable polygon for receiving a light beam from a source and for scanning the beam through a predetermined angle, and optical elements between the polygon and receiving medium for directing the beam to the receiving medium. In order to provide a very high resolution scanner which can be used to generate half-tone images, the optical elements include a first lens element having two spherical surfaces, a second lens element which has orthogonal cylindrical surfaces, and a cylindrical mirror.

摘要： An f-.theta. lens is disclosed which is particularly suitable for use with a color laser printer in which beams of different wavelengths are combined into a single combined beam. The combined beam is scanned by a rotating polygon onto a receiving medium. The f-.theta. is adapted to operate with optics for shaping the beam in a scan direction prior to the polygon and a cylindrical element after the f-.theta. lens to image the beam in a cross-scan direction onto the receiving medium. In order to provide an f-.theta. lens which is color corrected, the lens includes means for correcting in a scan direction for lateral color aberrations in each of the beams, and means for correcting in a cross-scan direction for axial color aberrations in each of the beams.

摘要： A beam splitter for color imaging apparatus is disclosed. The beam splitter comprises two prism elements which are joined together with a dichroic interference filter interposed between the two elements. An input beam to the beam splitter is divided into a first output beam which is reflected from the filter and a second output beam which is transmitted through the filter. In order to provide a beam splitter of a generally triangular cross section in which one of the output beams has the desired spectral content for a luminance channel in the imaging apparatus and the other output beam has the desired spectral content for a chrominance channel, the interference filter is formed of alternate layers of SiO.sub.2 and TiO.sub.2 and is disposed such that an input light beam to the beam splitter has a relatively small angle of incidence on the filter.
