    Abstract: A beam splitter for color imaging apparatus is disclosed. The beam splitter comprises two prism elements (12, 14) which are joined together with a dichroic interference filter (15) interposed between the two elements. An input beam (30) to the beam splitter is divided into a first output beam (32) which is reflected from the filter (15) and a second output beam (34) which is transmitted through the filter (15). In order to provide a beam splitter of a generally triangular cross section in which one of the output beams (32) has the desired spectral content for a luminance channel in the imaging apparatus and the other output beam (34) has the desired spectral content for a chrominance channel, the interference filter (15) is formed of alternate layers of SiO2 and TiO2 and is disposed such that an input light beam (30) to the beam splitter has a relatively small angle of incidence on the filter.

    Abstract: An illumination system for a film scanner is disclosed which comprises a light source (14) and optics for providing a line of light on a film (44). Light transmitted through the film is imaged onto photosensor elements such as CCD arrays (50, 52). In order to obtain a high quality electronic image, a xenon light source is used, color filters (26, 28, 30-32) are included in the system to control the spectral content of the light provided to the film gate, and an integrating cylinder (34) is used to provide a line of diffuse light on the film (44).

    Abstract: A mount for an optical element is disclosed in which an optical element (121) can be adjusted to a plurality of positions to change the position of an output beam. In order to provide a mount which can be adjusted to precisely position the output beam in orthogonal directions, the optical element (121) is mounted in a holder (120) which is rotatable about a first axis (Z'), and the holder (120) is mounted on a support (116) which is rotatable about a second axis (Z). When the optical element (121) is rotated about the first axis (Z'), the output beam is adjusted along an arc in an X direction; and when the support (116) with the holder (120) thereon is rotated about the second axis (Z), the output beam is adjusted along an arc in a Y direction.

    Abstract: A laser printer (10) is disclosed which is adapted to be used for color imaging. The printer comprises three diode lasers (58), each of which emits at a different wavelength. Each laser beam is passed through an apodizing mask (97) to trim the final spot size. The beams from the three lasers (58) are combined by the use of dichroic mirrors (18, 20) to form one combined beam. The combined beam is shaped by two spherical mirrors (30, 32) and is scanned onto a receiving medium (46) by a polygon (40). The receiving medium (46) is sensitive to the infrared, and the diode lasers (58) are selected to obtain the widest possible spectral separation in the light beams from the lasers.
